I have done as you requested and then restarted the server. There was no php error log being kept so I fixed that. I dropped all tables from the db and ran the install again. Same result. No php errors are being recorded either. I hesitate to include the phpinfo since it is so long and there does not seem to be a way to attach a file, so I will only include the top part of it. If you really want more info, I can include later.
