Hello!
I hope anybody can help me. I am running Mediawiki 1.28.2 with PHP 5.6 on www.kempedia.de.
Yesterday I recognized, that I get an error when I want to preview or save a page that contains a colon at the begin of a line to produce an indentation.
The error is
Forbidden
You don't have permission to access /index.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
And the administration-panel shows the error
Cannot allocate memory (client: 78.46.16.76:xxxxx) Couldn't create child process opt/suphp/sbin/suphp for home/web1807/public_html/api.php
After searchin in the www I thought it is something regarding mod_security(what is that?) or anything else regarding apache. But the technical support said that it comes from the actual version of mediawiki. "In der aktuellen Version vom Wiki werden Sonderzeichen transformiert übersendet, was bei bestimmten Sonderzeichenkombinationen einen 404 Fehler im Browser verursacht". In English: In the actual version ... special characters are sent after transformation. That causes with special character combination a 404-error in the browser"
Can you confirm it? What can I do that my wiki runs like before?
Thanks and best regards
Rainer Hamm
