Hi,
it looks like there is nobody who can work on a bug or production error like this: https://phabricator.wikimedia.org/T316858
I don't think, that this is a production error but really a bug. If it's not possible to open a page ( https://de.wikipedia.org/wiki/Benutzer:Doc_Taxon/Test4 ) because of running into timeout, the time should be increased to open the page to get the content of this page.
Is there really nobody from WMF or a volunteer who can help me with this issue? If you know somebody feel free to name him/her for contacting him/her.
Thank you very much Martin (aka Doc Taxon) ...
