phpBB 3.2.x Update Tip

So, did you update a phpBB board to the latest version and find yourself facing blank white pages after it showed a successful update process? Did performing a full restore (files and DB) confirm that the board still works fine when using the old version?

You might think to manually clear the board cache directory, but one of the best things you can do is disable all extensions before you perform the update. I confirmed that a board running phpBB 3.2.3 was able to successfully update one version point at a time up to 3.2.6 – where it met the blank page ordeal. This was done after seeing the issue after using the 3.2.3 to 3.2.7 single update package initially.

After disabling all extensions, running the single update from 3.2.3 to 3.2.7 worked fine. Best of all, I was able to re-enable all of the most important extensions without issue. The other 10-20 or so (I didn’t count) I just did away with. I’m unsure if activating extensions one at a time would have eventually revealed the blank page issue again, so I can’t say if reactivating all of the extensions would have been possible.

It is also possible that updating all extensions before updating phpBB itself might avoid the problem, as well, but I get the impression that removing the extensions from the picture altogether provides the best likelihood of the update going smoothly. I just wish the phpBB extension management page had a way to check-box multiple plugins and (de)activate them all simultaneously.
