Breaking: #73763 - Removed backPath from PageRenderer¶
The PageRenderer class responsible for rendering Frontend output and Backend modules has no option to resolve
the so-called backPath anymore. The second parameter has been dropped from the constructor method. Additionally
the public property
backPath as well as the method
PageRenderer->setBackPath() have been removed.
Calling the constructor of PageRenderer with a second parameter, or setting PageRenderer->backPath has no
effect anymore. Calling
PageRenderer->setBackPath() directly will result in a PHP error.
Custom installations using the PageRenderer API directly in an extension.
Simply remove the call to
PageRenderer->setBackPath() in your own scripts.
