I have same problem and I change all the value in the following files
PHP.ini
.htaccess
wp-config.php
and still get the error

Yes, of course, but I am tired of trying to fix this problem and every time it’s shows another problem with it.
I think it’s the time to take a backup, then reinstall it again.

but what is the best way to make a backup for posts and comments? “those are the most important things when I backup”

I already deactivate all plugins, But I’m not able to add categories and tags as well. Do you recommend to reinstall the wordpress ?

@MishaelH, still not work !! also I cannot add any tags!?

any one ?

Yes mercime, that what I did.
when I said cPanel i mean the admin control panel as you said from the dashboard.

thanks guys, I solve my problem
