Any error in PHP scripts causes "Internal server error". I used to work for a long time with my current project and it worked fine but I had to upgrade XAMPP package and thus PHP and apache too. Now when there is an error somewhere I can only see "Internal server error" while in the error.log there is a normal error message. I checked php.ini and saw that "display_errors = On" + "log_errors = Off". There no any problems with file permissions nor anything that could override the settings within the project. I'm pretty sure because I worked on this project before the upgrade and everything was fine. Plus if there are no errors in the scripts everything also works.
Please help! Working like this is pain... :(
