Getting 500 errors when trying to edit text

[drago]

Hello everyone,

For whatever reason, when I try to edit anything on the Pages editor, once I push save I get the following message

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

I have installed FCKeditor 2.6.4.1, however that happens even when I am using plain text.
I have tried to upload some of other folders to see if the error is fixed, but I am having no success.
I am using version 1.3.9f, and my hosting is GoDaddy
Any advice will be greatly appreciated.

Thanks in advance!!!!
