"Failed to open dir" error when generating a PDF file with TCPDF

I'm trying to generate a PDF with TCPDF. I have the data to render in the PDF, I created the controller for that, but I'm getting the following error:
Warning: opendir(/home/symfony/pricing/web/tcpdf/fonts/): failed to open dir: No such file or directory
500 Internal Server Error - ContextErrorException
I don't know where it comes from.
Any suggestion?
Thanks!
it means opendir() can't find the directory supplied. try to search your files for 'web/tcpdf/fonts/' to locate that code and supply the correct location of the fonts

compile error lyx var/folder does not exist

When I compile the lyx document to get the PDF I receive an error message
/var/folder..... does not exist
that is the start of the temp directory root but for other files I didn't received this error message.
Help required.
Go to Tools > Preferences > Paths.
Under "Temporary directory", put "\private\tmp".

Wordpress Images upload error "Failed to write file to disk."

I am having following error:
Failed to write file to disk.
When trying to add featured image or add media, image progress bar completes with error and no image is uploading.
Have changed permission of uploads directory to: 777
but no luck.
There are three common causes :
upload directory permissions - not the case here
the server's hard drive is full / your quota has been exceeded
the server's tmp folder is full
