I upgraded a site from EE 1.6.8 to EE 2.4.
The EE 1 site had numerous add-ons, a few of course didnt have EE2 equivilents.
Upgrade went smooth except, I am receiving two errors. Only see them when logged in as Super Admin (errors for Super Admin turned on of course), but the site when viewed logged out or other browsers seems to work fine.
The errors are in the attached image.
The first error, I have no idea what would be causing it. I have tried reuploading the Template.php file thinking it was corrupted during upgrade, but that did nothing.
The second error, I have come to find out it has to do with the Generate HTTP Page Headers under Output and Debugging being turned on. I turn it off and it disappears. But in all ee installs I have done this is always on.
Also in Output and Debugging both Enable GZIP Output and Force URL query strings are on as well.
I turn off Force URL query strings, nothing is fixed. But if I turn off Enable GZIP Output, the site becomes viewable but that error is still at top of the site.
What could be causing the issue?
Previous add-on, something the database?
Thanks much in advance!
