Will do @bobsled. However, such a type mismatch (parameter doesn’t implement Countable) shouldn’t be so hard to find and fix …
This is also my assumption @bobsled … just wanted to know if I have to look also for something else.
Bonus question: I also get several messages like this one:
Warning: Cannot modify header information – headers already sent by (output started at /homepages/9/d141745617/htdocs/misc/wp-admin/includes/plugin.php:1392)
referring to the same line in plugins.php. Are those triggered by the original one and will disappear once the root cause is fixed?
Same here. It’s only an annoying warning though.
