I've tried MySQL 5.6 and MSSQL 14, ssl and sans ssl, I've made the cache, files, and images (avatars) folders user writable.
On php 5.6 with every packaged extension enabled. Tried 7.0+, but phpbb doesn't seem to use the pdo mysql extension over the standard mysql.dll extension, so stuck with 5.6. Logs don't show anything.
Everything seems to work fine, aside from posting. Any time I try to post, I get an HTTP 500 error.
Anyone able to help me?
(Can give ftp, panel, and direct RDP access if needed. (Snapshots already taken.)
