Hello @er2es and thanks for the report. That's a very strange error. My first thoughts are the plugin download was corrupted or not complete… Can you try to manually update it and tell me if all needed directories are here? Thanks.

Hello @Pierre-Lannoy!

Thanks for quick reply.

So the ""DecaLog\Engine" not found" is my fault, i rename the plugin folder after the 500 error, and i forgot to rename it back ( i think) - so this is not relevant, cant reproduce.

However i debug the second part the log: "PHP Fatal error: Allowed memory size...." On our test envroiment i can reproduce this, after the plugin is activated. I think the problem is here: https://github.com/Pierre-Lannoy/wp-apcu-manager/commit/5018fc6835d8a89e845943ffd9ddf4d4c0d9762a#diff-2d61cb87c3e9ded3fd8a74e7fdf7d799aaaa59e00d2fc678c15375c362d0c35cR961 with the get_current_network_id() call. If i write '1' instead of 'get_current_network_id()' then the multisite work, otherwise get PHP Fatal error: Allowed memory size....

On the previous releases i cant find this function call (get_current_network_id()) - that's why I think this cause my problem

[Pierre-Lannoy]

OK. Your assumption seems right: if replacing get_current_network_id() call with a static value make the issue disappear, this call is the cause of issue. Let me investigate it…

[Pierre-Lannoy]

I confirm I can reproduce it. It's a bug. Currently working on a fix…

[Pierre-Lannoy]

Issue fixed @er2es . I will now monitor hit-rate evolution on my (multi-site) test instance and release the new version (3.7.2) before today 16:00 CET…

[er2es]

@Pierre-Lannoy thanks for the fix and the otherwise great plugin!

[Pierre-Lannoy]

You're welcome. If you like it, do not hesitate to make a review on wp.org 😉 BTW: the new version (3.7.2) is now released and distributed by wp.org directory. Can you give it a try and tell me if it fixes the mentioned issue?

[er2es]
