Courspres Pro units not loading..need an answer asap

Hi there,

I need some help figuring out why our units on CoursePress Pro are so slow to load and causing a time out error. I've already contacted our website hosting service and they have assured me that we are not using too many resources on their end. They reckon there is an error in one of the PHP files....read below:

Hi Dean I use uber to host my website. Its online-units.sprout.org.au and there is a very long delay in loading some pages.
Erika: at 11:51:10
Also when the pages dont load at all I get an Internal Server Error that reads: The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator at webmaster@online-units.sprout.org.au to inform them of the time this error occurred, and the actions you performed just before this error. More information about this error may be available in the server error log. Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Let me have a look at this for you

I am just checking the error log for you now
Dean: at 11:53:57
the site seems to load fine for me now

Its just that you are not a "student" so you cant see online units which are the slowest part to load. I could quickly make you a user so you can see what I am talking about

There are some issues with the plugins that need to be addressed by the developers of the site

This error log can be viewed in public_html/online-units/error_log

this should assist with troubleshooting the issue from your side
Dean: at 12:01:21
You are not overusing resources or anything like that, there is just an issue with the capabilities.php file (on line 781)

You're most welcome Erika

If there is anything else, please feel free to jump back on live chat.

We need this addressed as soon as possible as these units are going live to our students next week.

Also, I can't really see any difference from upgrading and purchasing CoursePress Pro yesterday. I followed your instructions and downloaded the zip Dashboard file, uploaded it and activated it. My dashboard just tries to get me to upgrade through a pop up box and all the other settings seem the same in CoursePress Pro. We just paid $294 for a year of membership I thought, have I done something wrong?

For ease of troubleshooting here are our login details:

and I've attached our error log to this email as well.
