Thread:Project:Support desk/Update previous MW 1.16.5 to 1.17.0 throws an 500 internal server error/reply (32)

Thanks for your help. the language files were correctly updated, but like 'Emufarmers' suggested before, we too had the Vector extension installed under 1.16 and after the upgrade. removing it and purging the cache doesnt seem to be make any difference. any suggestions on how to proceed?
