I have several CPT and I noticed that since I have now 100+ posts in some of them, the WP backend loads really slow but just in these CPT.
Other sections like Plugins, COmments, Settings etc. works properly.
Pages is slow as well …
Following this question I removed the hierarchical parameter, without any results.
I don’t have any special plugin installed, just ACF and a chaching plugin. I tried deactivating all of them but same results. The PHP version is the most actual one, memory limit is set to 512mb.
What can be the issue here?
PS: the Theme I coded myself
