not acceptable?

thats caused by mod_security.

if you do not have an .htaccess in your wp-admin/ directory:

create a text file on your desktop:

put the following inside it:

<IfModule mod_security.c>
SecFilterInheritance Off
</IfModule>

name it whatever you like and 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:

Edit it and add:

<IfModule mod_security.c>
SecFilterInheritance Off
</IfModule>

—

there are cases where that might not work — for instance, mod_security was recently changed so you might need a different little snippit of code. if this doesnt work, just post back.

and be careful with your edits, obviously.

Hello, i have the same problem with my wp-installation (not-acceptable-error on the background start-page and when i am trying to create a new category), but your suggestion to set mod_security off does not work on my webserver. I tried zu alter the .htaccess file in both folders, the root folder and the wp-admin folder.

The support of my webserver is totaly incompetent and doesnot even know something about the not-acceptable-problem.

Is there an other possibility to solve it.

GREAT! This was exactly what the doctor ordered for me too.

Thanks for taking the time to post such a helpful comment whooami!

youre welcome ??

I can’t create categories either. When I tried it with the .htacces file, I couldn’t even access my admin panel anymore, so I deleted it again.
Is there another solution?

Is there another solution?

Yes, there is an other solution: change your hoster!

That was the solution for the problem described by me.

The snippet of code above in a .htaccess file but it does not work for me. Is there any other options other than changing hosting companies?

Maybe you need to read it again. It is NOT supposed to be in your main .htaccess but in a separate .htaccess file in the wp-admin folder.
