hi, paolo,
I disabled the GD booster. In Firefox, I also don’t get any errors.
Now the error message in Opera changed, showing simply the original path to the file:
Failed to parse SourceMap: http://iallgaeu.de/wp-content/plugins/geodirectory/geodirectory-assets/js/jquery.barrating.min.js.map
In Firefox a get an error that a stylesheet couldn’t be loaded – the fontawesome.css from maxcdn.
Have you seen anything like this before?
I was installing the Affiliate Plugin and its Geodirectory Add-on, as well as an online chat plugin.
I cannot say if they are related to the problem as I deactivated them but this didn’t change the current situation. (Of course all caches were cleaned before every new check.)
Looking forward for advises.
