403 error when changing config

[chickendippers]

Hi there,
Whenever I attempt to change my gallery configuration I receive a 403 error - I can't say when it started happening, however it hasn't always done this.

I was previously running version 1.4.2, I thought the problem might be caused by my upgrading both php and mysql to version 5, so upgraded (using Fantastico) to version 1.4.10, however the problem still persists. I have read that the Fantastico upgrader isn't perfect but I'm not sure if my problem is related to that.

My gallery can be found at www.cncworld.org/gallery


Thanks in advance,
chickendippers.

Probably mod_security. Ask your host for instructions how to disable it if so.

That did the trick. Thank you so much

For others, I had the same issue and you can try to add the following into you .htacces file

To disable mod_security completely, add the following line to the .htaccess file.

SecFilterEngine Off

To disable HTTP POST scanning only, use the following instead:

SecFilterScanPOST Off
