Getting a 505 Error When Trying to Make Posts

Hi there,

So I purchased a theme on themeforest titled ‘Ettiquete’, a client really liked the layout and setup and I am stuck with it. I can’t change or the theme, she really likes the theme.

So I initially had the latest version of WordPress installed on the hosting account (my client’s hosting and domain are all on godaddy) and I installed the theme, everything worked fine until I noticed that I could not make posts, add slides or portfolio pieces. I noticed because when I pressed ‘add new’ for these post items, I would get a 505 error (see screenshot here) – I called godaddy, who after almost 3 hours on the phone managed to point out to me that the issue is coming from the theme, because if I de-activate or uninstall the theme, everything works fine with making posts. After trying to communicate with the developer of the theme (and not getting any useful feedback), I noticed that the theme was originally optimized for versions 3.0 and 3.1.

Because of this, I decided to downgrade and manually install WordPress 3.0 – so the current setup is under http://www.gabriellaarango.com/newweb/

After all this, I tried to add a new post / slide / portfolio piece – and I am STILL getting the same exact 505 error.

Has this kind of problem ever happened to anyone? I am getting very nervous because like I said, my client really likes this theme – to the point where almost all of the graphics have been created around this theme.

Could anyone be willing to help or re-examine this with me?

I would greatly appreciate it.

Regards,

Marcus
