My log file filled out all the disk space and now some parts of the website are not working

My log file filled out all the disk space and now some parts of the website are not working. There is enough free disk space now and i rebooted the server but not sure how to solve this problem.

For example /ee-admin/ shows as 403 and PMA as 404 not found and ioncube loader is not working. This looks like a problem with PHP?

Any ideas?

I have fixed admin tools by running ee admin-tools disable and ee admin-tools enable.

However ioncube is still not working…
