I'm with a problem, when make uploading image with the Advanced HTML Editor 3 editor in served gives me the following error:Not Acceptable!An Appropriate representation of the requested resource could not be found on this server. This error was generated by mod_security.Know how to solve my server is hostgator.Thanks in advances

Hello Eliana,

Most probably your host has mod_security enabled. That error is specific for that mode. That mode is considered as network layer firewall for requests and it contains specific rules. If a request does not fit those rules is considered a threat for attack and is rejected with the error you have posted.
What you can do is to check this with your hosting provider and see if it can be disabled for your site.

Regards.

Thanks

I contact my provider and he change de rules of firewall efectivale the difficult is because this. But now i have new error is this:
The following error(s) occured:

• This folder is not authorized for upload!
Please make sure it has write permissions and the authorization file is in it.
i give premition 777 and the files upload_authorize_for_dmxEditor is inside of the folder
Thanks

Hello Eliana,

Do you have a mod rewrite set in your .htaccess file? Something that will change the path of the requests?

Regards.

the problem is because I call the form from table to include, and I direct access to the form, the error no longer. Why gives error with Include?
Regards

solved, what happened is that to get the form through include, he changed the path to the upload folder

Hello Eliana,

Yea, when used as include the path gets parent page as reference. Thus the original path changes and thus the problem. Glad you have that sorted.

Regards.

Thanks for your Help and Availability
Best Regards
