Hello,
I also had the problem that I couldn't login any more due to the cron entries in the database.
I followed the steps of Otto on the first page. Now the site (backend) and everything works fine! Thank you for the instructions!
I'm only wondered about one point: Before I followed the steps I looked into the source code to find out which version of Wordpress currently runs on my webspace: It was 4.3.
After I "patched" the installation with the help of the above post, Wordpress says that now 4.3.1 is installed.
Is that normal?
Thanks in advance for every reply!
