Apache to Litespeed Wordpress Migration - wordpress

I’m hoping I can find some help here. I have setup cyberpanel/litespeed and I’ve migrated my Wordpress site using Duplicator over from an Azure App Service (Apache based server). Since I’ve migrated over to Litespeed, I have been inundated with errors all over the site, most of them include these two:
Uncaught Error: Call to undefined method …
Parse error : syntax error, unexpected ‘endforeach’ (T_ENDFOREACH)
Why would my site run seamlessy on Apache, but after migration all these errors are produced? Is there some kind of configuration I need to do?
Here are the server details:
Apache Server: PHP Version 7.4.26
Litespeed Server: PHP Version 7.4.29
Any help is appreciated.
Many thanks

Using uninitialized "redirecttoindex" variable

Suddenly out of nowhere I can not log in into my WordPress site. The site is working but wp-admin is not. In the error log I get:
2022/07/04 23:45:58 [warn] 31793#31793: *300658 using uninitialized "redirecttoindex" variable, client: ip.000.000.000, server: mydomain.com, request: "GET /wp-admin/HTTP/2.0", host: "mydomain.com"
How can I debug this? I have just got this site for maintenance and I am not very familiar with WordPress. Should I diff it with the original version and see if files are modified?
I scanned the code and there are no redirecttoindex variables. Is something up with nginx?
I also can not find anything on google with such a query.
Server API: FPM/FastCGI
PHP Version 7.4.26
nginx/1.20.2
You confirm the other pages in the sites this working well ? If the answer is Yes, you need the check if exists some plugin what redirect the route of wp-admin for new route. First we have to activate the debug mode in the wordpress in the file wp_config find de const WP_DEBUG and set true.
P.S: Don´t activate the DEBUG in the product view.

Changing .htaccess in wordpress file gives an internal server error

So i'm working with the wpmudev snapshot plugin which gives an 'max_execution_time' warning (30 is to low), when I update this to 180 by adding
php_value max_execution_time 180
to the .htaccess file (wp root) my site gives an internal server error. Is there an reason why this happens? And how can I fix this?
your code is correct and refer below scenario,
Check with your error log and if it is a PHP error try to troubleshoot that.
what is your server engine, because Apache engine only have .htaccess file others like nginx not support .htaccess file
If not got solution check with your hosting before that make sure your site not have an issue.

Moving Wordpress website to another server

A friend of mine asked me to move wordpress website from development server to production. I've copied all the files, backed up and restored database. After that I'd changed sitename and home values in database (_options table) to new domain and it started. Though only home page is working fine. When I navigate to any other page it gives me 500 error. In error_log I got following errors:
1423021301: /home1/crankst1/public_html/fish-dev-site/ssv3_payload_extractor-r0Xkqq2xFD.php startup
[24-Feb-2015 19:16:59 UTC] PHP Warning: require_once(/home1/crankst1/public_html/fish-dev-site/wp-content/plugins/js_composer_theme/include/classes/core/class-vc-sort.php): failed to open stream: No such file or directory in /home1/crankst1/public_html/fish-dev-site/wp-content/plugins/js_composer_theme/js_composer.php on line 168

Paths that cause errors are related to development server and I can't find where to change them. I'm not very good with wordpress, so I suppose that solution should be very simple.
I'm sure there is an issue with a plugin http://codecanyon.net/item/visual-composer-page-builder-for-wordpress/242431/comments?page=149 try to see if there are any hardcoded paths on the plugin dashboard.
Delete your .htaccess file then go to the permalinks page change to another permalink type save page then change back to permalink you had this will force wordpress to recreate the .htaccess file and it will allow all pages you have to show correctly on the site. :-)

Symfony2 on nginx shared hosting

i've a symfony 2.3.16 project which work great on localhost.
But today i wanted to host it on my remote server : its a shared hosting on nginx 1.4.7
i've changed the public folder (from /web to /public_html : still working great on localhost)
i've cleared then deleted the dev and prod cache,
added my remote IP to app_dev.php and activate the debuger in app.php
and then uploaded all files to my shared hosting.
the tree is like this :
app
bin
public_html
- bundles
- app.php
- app_dev.php
- config.php
- .htaccess
src
vendor
and when i try to access some pages, i've always ended with a 404 Not Found error.
here, you can see : http://dojonantais.cwebh.org/app.php/admin/
i have no route defined for /
my app/config/routing.yml is like this :
dnAdmin:
resource: "#dnAdminBundle/Resources/config/routing.yml"
prefix: /admin
also, when i try dev environnement http://dojonantais.cwebh.org/app_dev.php
it says there is no route for /, which is logic, but i've another error with the debug bar :
An error occurred while loading the web debug toolbar (404: Not Found).
Do you want to open the profiler?
and when i open the profiler : 404 not found
again, i can access the config.php and it says my server is ok to run Symfony, but cant access the configurator (404 error)
So, what is missing?
Thanks again.
So, problems coming from my remote host on nginx.
i change the host to a 1and1 server and all is ok.

Apache 2.2.16: client denied by server configuration

I have problem with my server configuration. I use Apache 2.216, PHP 5.3.3 and wordpress 3.4.2 with Shopperpress. Time to time I receive error "client denied by server configuration: path/to/file" in apache log file. It is path to _tbs.php file, but it is not problem in rights of file, because this file is called 12 times on page for getting thumbs of photos and there is error only several times. I think that it has no connection to concrete photo, because once this photo is displayed corectly and next time same photo produce error.
Do you have any idea what can be reason?
Thank you for all advices.
Viktor
I think thats a problem by the configuration of MaxClients or MaxRequestsPerChild.
Try to restore the default configuration and try it again. If that not works, reinstall Apache and purge the old configuration.
You have given very little information. It is not clear under what conditions do you work (OS, installed modules, Log entrys,...).
WordPress 3.4.2 is very old and safety-relevant. Please update WordPress and your WP-Plugins.
Go to you VHOST-file and replace:
Deny from all
Allow from 127.0.0.0/255.0.0.0
with:
Require all granted
This cause for old Config-Files and newer Apache-Version. Since Apache 2.4.3 a new security feature is added.
