Old MediaWiki site broken in Chrome - css

On Chrome I have a MediaWiki 1.13 installation that works on Firefox and IE 11, but the left menu appears below the content in Chrome.
How can I fix this without upgrading MediaWiki?
EDIT:
Found a similar question.
Also found a compatibility page on Wikipedia that implies that older versions of MediaWiki do not support Chrome.
Appears that the problem is server-side and I need to get the admins to upgrade to version 1.16 or above.

My install was fixed by commenting out the contents of KHTMLFixes.css, as per https://code.google.com/p/chromium/issues/detail?id=28267

Why wordpress show me two version the same site

I am using WordPress to build a site, but actually have a problem, the site don't update at all. For example, I update some data in a box, on pc can see the update, but in mobile don't.
Browser pc version
Mobile version
Update 1
Searching a little more, I could find that typing the name of the page in google, and checking a little more, I could find that there is a cache that leaves the page hosted in google, the strange thing is that I am using Firefox.
Update 2
I prove the page in 5 browsers in the desktop and work fine.
Firefox normal and developer edition
Chrome
Edge
Opera
Vivaldi
I do a search about the page on google, and see other problem. I was using a plugin for maintenance mode, and deactivate, and still appear the message as principal and not logo for the Google.
When working with Wordpress make sure use common browsers like Chrome and Opera. When your work isn't updating make sure you clear the cache of any caching plugin on the website and that of your browser(found in settings), if you are still in doubt then you can view the page on Incognito(Ctrl + Shift + I) for chrome on PC

Issue with website displaying in Internet Explorer

I am having an issue with my WordPress site designed with the Elementor plugin and Ocean WP theme. It displays perfectly fine in Chrome, Firefox and Edge. However, it doesn’t display at all on Internet Explorer 11 – only one picture is visible and headers/footers etc don't display.
I’ve tried to look at plugins etc but can’t find the reason for it. Can anyone please suggest some solutions? I have also tried to look at the code but can't see what is causing it to break when attempting to display in Internet Explorer 11.
Thank you all in advance!
Your site is showing several errors in the console of the IE 11 browser.
The issue can be caused by the WP theme or Elementor plugin.
It can be possible that one of these 2 things using any modern features that are not supported in the IE 11 browser.
I found the below information on the Wordpress browser issues page.
Internet Explorer: Due to browser incompatibility, some themes are not
fully functional in Internet Explorer 10 or earlier. If you are using
Internet Explorer 10 or below we recommend upgrading your browser for
an optimal experience.
I found the below information on the Elementor requirements page.
Most features will display properly in IE but because IE is an older
browser, it is incapable of supporting some of the modern web
technologies that Elementor may utilize for some of its features.
Below are the links for the support pages of the Elementor and Wordpress. You can also try to know their opinion on this issue. It may help you to narrow down the issue.

Font-awesome fonts proving problematic with IE11

We are using Font-Awesome 4.0.2, and have been doing so for about 18 months. Just recently, with IE 11.0.9600 17843, we have noticed intermittent rendering issues. We can CTRL-F5, and the fonts appear, then go off the page and return and find some fonts absent. When you hover over them they reappear.
On some instance of the same IE11 browser(64bit not 32bit) it works fine. We have checked the security settings ie fonts can be downloaded.
There is no issue with Mozilla or Chrome.
Weirdly the problem exist with the live site and not the QA site. Both are on the internet.
I have have researched this, and the intermittent nature is the key, and it may point to a bug in a recent IE11 update, since this did work with IE11.
Advice appreciated...
Should we update to the newest Font-Awesome ie 4.3, or is this newer version just contain more fonts?
Thanks in advance.

Wordpress Image Editor issue in IE7

Anyone knows why WP Image Editor is not working in IE7? IE7 would just crash every time I click on the Edit Image button.
I do not see this problem in other browsers, only IE7.
I tested using WP 3.4 and the latest 3.4.1 and get the same result.
Any idea how to fix this?
Thanks!
Edit:
I was wrong about IE7 deprecation in admin. I also was able to confirm the crash using a virtual machine with IE9 set to IE7 document and IE7 standards mode.
Updating one of the external libraries fixes the issue on my end. See the updated ticket for the patch. Could you please test this patch and see if it resolves the issue for you.

Update wp-includes/js/imgareaselect/jquery.imgareaselect.js with the updated version from github to test.

What Internet Explorer settings could cause IE7/IE8 to not load css?

We have received isolated reports of IE7 & IE8 not loading/parsing the css from our website built on asp.net 4 and hosted on iis 6. One user recently sent us screen shots to confirm the problem.
They tried upgrading from IE7 to IE8 which did not fix the problem.
Firefox installed on the same computer would load the website/css normally
After investigating we found that resetting their Internet Explorer's settings fixed the problem (Tools -> Internet Options -> Advanced -> Reset). He is now unable to reproduce the problem
We've tried to reproduce the problem with the advanced internet explorer settings on our computers without success. Any idea what setting could have caused this problem? Any experience with similar issues? Thanks!
I have seen similar problems with various versions of IE due to malicious or poorly coded add-ons. Next time you see this you should try having them run IE without add-ons to see if the problem still exists.
