OIOpub Forum » General  »   Purchase.php 500 internal error

For some reasons after 2 updates of the plugin (I have downloaded the latest update and I installed it), my purchase.php gives a 500 internal error when clicked. FYI: I have not changed a single setting but only updated the plugin. >> It used to work very well during months..

My wordpress version is: 2.3.2
My plugin version is: 1.62-u260

wp-content rights are 777
OIOdirect plugins are 755

PS: I tried setting 755 to wp-content it did not solve the problem

I'm trying to think of all the causes of this that I've come across:

* directory above OIO directory has permissions set to 777
* htaccess file contains entry preventing php pages from being accessed in plugin directory
* OIO files themselves writable (permission of files should all be 644)
* auto-upgrade (via 3rd party script) screws up permissions / file ownership

To answer your question, all files should be 644, and all directories 755. If none of the above scenarios apply to you, the next thing to do would be try and reach a text file in the OIO directory (readme file for example). If you can reach it, then it's a more general problem (most likely permissions), otherwise it could be an issue related to restricted access of php files.
