Sorry to take so long to get back, I just took a long course on setting up the .htaccess file. Got things pretty tightly locked down and no errors.

I am still going to run the Akeeba database tool just to make sure it isn't some corruption in the database.

I have already combed through the template and can't see anything there.

So I will keep looking.

Fotis, I am still working on this problem, though I have found that by deleting and recreating K2 categories that I the page displays correctly again. Still some pages seem to not respond to that solution.

If I access the page this way:

www.911tap.org/join-us/find-your-tap-coordinator

The page displays correctly;

If instead I access the page using a parameter string like:

www.911tap.org/index.php?option=com_k2&view=item&layout=item&id=777

I get the following error code:



Note: I had to add an exception for images/temp, in order for access to this image to be allowed.

As you suggested previously using Filezilla's element inspector->Network tab, I get the following:

Request URL:	www.911tap.org/index.php?option=com_k2&view=item&layout=item&id=777
Request method:	GET
Remote address:	199.116.77.184:443
Status code: 500	Internal Server Error
Version:	HTTP/1.1

Using the Joomla Router generated URL to access the page I get the following HTTP response.

Request URL:	www.911tap.org/join-us/find-your-tap-coordinator
Request method:	GET
Remote address:	199.116.77.184:443
Status code: 200	OK
Version:	HTTP/1.1

Note: find-your-tap-coordinator is item 777.

I will finish this later. right now I have to shut my computer down and reboot. I will finish this after I save and reboot.
