Greetings everyone,
While upgrading OJS from 3.3.0-16 to 3.3.0-18 on our staging server, I stumbled upon some weird errors I’ve never seen and that aren’t obviously covered in the forum.
For both this upgrade and the previous one, I proceeded with the compressed versions on PHP website (e.g. https://pkp.sfu.ca/ojs/download/ojs-3.3.0-18.tar.gz).
First weird error, some plugins in my 3.3.0-16 were at a more recent version than the plugins that shipped with 3.3.0-18, which resulted in a “Downgrades are not supported” exception when running the upgrade. Never seen that. I fixed that one by simply swapping the directories for the plugins with a version problem.
But then, second weird error: when the upgrade process reaches the post-install stage, it throws this message:
2024-07-24 09:49:07 [post-install]
<h1>Trying to instantiate a "metadata" type description with an invalid type name "APP\plugins\metadata\dc11\schema\Dc11Schema(ARTICLE)".</h1>ojs2: Trying to instantiate a "metadata" type description with an invalid type name "APP\plugins\metadata\dc11\schema\Dc11Schema(ARTICLE)".
The problem seems again to be related to a plugin. I could try and swap that directory too – but at this point, I fear I’ll just get another exception when running the upgrade. I’d rather understand the source of that plugin problem before further messing with the directory structure.
Any hint?
