Hey Guys,

I installed my boards under PHP 5.5. Well I am having to use 5.3 for other applications but when I change over I get 500 Internal error. Is there away to revert boards to be compatible with 5.3?

cause for internal error should be traced through the error log (if available at web host control panel)
it would be better to contact your web host for fixing it.
