Matomo WP-Plugin produces Type E_Error

Hi there,

for several weeks I have been having problems with the Matomo WP in that it crashes the entire site. I have seen that others have had similar issues and I tried various proposed solutions from other threads but nothing has worked yet. I am quide desperate, which is why I am posting the error log here in hope for help and/or pointers, thank you a lot in advance:

WordPress-Version 6.2

Any pointers or help is very much appreciated.

Hi, I am having the same issue with one of my client’s website. Did you find any solution?

Hi, I did not find any other solution than to downgrade Matomo to version 4.10. which now works.
