The site at https://de.wikipedia.org/wiki/Benutzer:Holger1959/HE-1 times out with the message:
PHP fatal error:
entire web request took longer than 60 seconds and timed out
If the site is loading please purge the cache (For @ToBeFree it worked until he purged): https://de.wikipedia.org/wiki/Benutzer:Holger1959/HE-1?action=purge
ToBeFree and me make the size of the data responsible for the error.
A possible solution as workarround is to clear the page by a system administrator.
Please call me the tag which sould be added next time if a technical problem appears.
