I am about to upgrade a site from Teline2 to Teline3.
I made a copy of my Teline2-based site. Then installed Teline3 and the new extensions.
After changing to the new Teline3-template, clicking on any link on the Start page gives the message “Internal Server Error. The server encountered an internal error or misconfiguration and was unable to complete your request.”
I have replaced the following files and now use new versions of these files fresh from the Teline3-package: index.php, component.php, templateDetails.xml. But I still get the same error message about Internal Server Error.
I have also disabled extensions such as JomComment och JReviews.
I guess there are lots of possible mistakes. This is the first time I have tried anything like this, so if someone has good advice or can help me fix this I would be grateful.
