[ad_1]
Hi! I see multiple topics, multiple answers and lots of code… I have (at least) 3 websites giving the critical error after the auto-update 6.2.6. Can’t figure it out with debug ( I see the Argument #1 ($callback) must be a valid callback, function “_wp_footnotes_kses_init” alot).
What to do?
Best regards,
Remco
