I have a site running on Drupal 4.7. Things are going well! I convert to clean URL's, and it works well! I install Pathauto, and it creates paths for me everywhere. Great. Then I re-pathauto'ed the site and I get a lot of strange url alias's. I dumped the url-alias table, and re-pathauto'ed again. Now I have a good looking list of url alias's and life is good, except, I cannot create new forum topics. Everything else on the site functions correctly, I can add stories and blogs, and edit them, but I cannot add topics to forums.
When I try to add a topic, 'node/add/forum/32', I can preview the new node, but when I submit, I get a white screen, ie no screen output from the site.
I looked in the drupal log for help on what is happening, and there are NO event loggings from the submit. I looked in the log reports from my hosting company, and I don't see any problem there either. No errors undates since the 26th, and I have been trying this for the last few days.
Pathauto or Clean URL's might be the problem, but might not be the problem. I tried to debug this and disabled Clean URL's and the problem did not go away. Ditto for PathAuto.
I need a scrap of something to go on and try to find the problem. Searching for 'cannot add new topics does not work, because that is on EVERY forum page as part of the instructions.
Thanks for any help on this one.
