All of a sudden, all my Mediawiki pages are blank. If I click the edit field, the content is still, there. Ive checked the sqlite file and it looks just fine. Ive turned on debugging output and get the following:

Are these errors most likely the cause of the issue? If so, how do I resolve it? And if not, anyone have any idea on what might be the problem?
Answer
Found the issue. Its described in this bug report. Its apparently fixed in the Mediawiki master. The released versions are not compatible with PCRE 8.34.
