I've volunteered to help someone who is running on a decade-old version of IPB and the problems are stacking up. His host has unceremoniously migrated him to PHP 7 which has, of course, significantly broken the forum. I have tried to use error_reporting flags in php.ini (multiPHP) and inside of the PHP files themselves, but despite several attempts, there is just no way to suppress enough error messages to get the forum fully working. The obvious approach to me would be to migrate to a host that is still running a protected PHP 5.6 just to get things running stable long enough to consider other options. So far he has contacted IP and they wanted a ridiculous figure to do an upgrade and then withdrew the offer once they took a closer look at the site. He asked about a less drastic upgrade, but it seems that IP has aggressively removed all traces of IPB3.x software and addons and, regardless of license status, provide no way to download any version other than 4.4.x. I should add that there is some question as to the integrity of the files on the site, but because the site was acquired through a sale, there is no clean download of IPB3.0.x available so it is not possible to restore the files to factory. This presents another problem. An obvious migration path for me would be to go to XenForo. The site is light on plugins, so I would setup a new forum, spend a few weeks getting the styles and overall look close enough and then perform the data migration. However XenForo's importer is not compatible with IPB3.0.x. The idea of a IPB3 -> vB3 -> XF2 migration gives me the willies. Just wanted to send up the Bat Signal in case there was some avenue I hadn't considered.
