Pitfalls

Wrong Entry Point

This extension needs an entry point with a protokoll and domain to proper fetch internal pages.

An entry point with just a slash ("/") will not work!

This value can be set here "Sites Module" > "Edit site" > "General" > "Entry Point".

If you e.g. use the introduction package, this value is set to "/" by default!

Self Signed Certificates

If you use a self signed certificate, you should also check, that "HTTP" > "verify" is set to "0".

This can be done under "Admin Tools" > "Settings" > "Configure Installation Wide Options" > Filter by "verify" > enter "0" > Press "Write configuration"
