Design link in admin area problem

I am getting the following message when I click on the design link in the admin area, I have tried changing the folder permissions to 777 from 755 and I have downloaded the fix powerstore4_011.

"Internal Server Error, this is an error with your script, check your error log for more information."

I have spent way to long on something that I purchased as a quick fix!

I have created a support ticket so we can look into this issue further.

Any extra information on this? While I am not getting that particular error, I am getting non-working page, which I posted as a separate thread. But these two threads may be related.

Thanks

Hi
Having exactly same problem here, have tried changing the folder permissions and uploading the update file supplied by WA, but keep getting the same message when I try and save any changes to a design (have alao redownloaded the PS4.01 files, reaceated the database, and finally trashed the hosting account and rebuilt, still the same errors). Any help would be much appreciated...
cheers

A similar thread here: showthread.php?p=92704#post92704

Just an update, had to get hosting provider to change the permissions, just one thing though they have said: "Do note that this leaves your site fairly vulnerable in terms of security, so it's best to keep an eye on it and make sure files aren't being injected, and that all software is updated to it's latest version."
Am I leaving my site vunerable?

I have encountered the same problem with the internal server error when I try to change the design of Power Store. Will a fix be posted in this thread?

Found the same thing plus this page: /webassist/plugins/shopping_cart/ipn.php
