I had a similar problem. Very frustrating. (I managed to catch Pm on 
chat and he diagnosed it in seconds.)

In my case, I narrowed it down to the word "open" about 300 words in. 
Earlier or later was fine, but not there.

Diagnosis: php security module was being over-cautious. It could be a 
php script trying to open a file it shouldn't!!

Work-around: replace the offending word with op[=en=] . The extra 
characters tell PmWiki to send the contents through without interpreting 
them. (Normally used for showing wiki-text in the documentation.)

Full fix: Set up a separate page showing the problem in the wiki for my 
host's support team and send them details of problem and diagnosis. Not 
sure what they did, but it my access logs show it took them 20 minutes 
and four tries.

Hope this helps,

Sandy
