I’ve been plagued with this problem for about two weeks now. I could write a post, I could publish it: but it would never show the information in the content field. The only thing that would publish would be the title, the tags and the categories. I could write comments and I could even delete entire posts: but I just couldn’t edit them. If I went into the edit field, I could type but once I clicked save the edits would dissappear.
Another sign of this problem was that I couldn’t switch to code mode: it was always stuck on visual editor. After some heavy searching I found two fixes, one safer than the other.
Option 1: Not Very Safe
IF YOU DO NOT HAVE an .htaccess in your wp-admin/ directory:
create a text file on your desktop:
put the following inside it:
save the file.
Upload the file to your wp-admin directory.
Rename the uploaded file to .htaccess (with the .)
IF YOU DO HAVE an .htaccess in your wp-admin/ directory:
save the new .htaccess
Option 2: Much Safer and focused directly on the problem:
I went ahead and edited my .htaccess in my root directory and added this:
That fixed my problem. I didn’t want to turn off mod_security for the entire wp-admin folder, so this way just turns it off for index-extra.php file.
