Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-related problems?
– resetting your custom permalinks to the default setting?
Why do plug in’s cause this problem?
Have you tried what esmi suggested?
yes it doesnt cause it but I still need a plug in to do the job 🙁
I need a plug in for SMS Alerts , a form plug in for user’s to fill out and also a email list plug in. Can you help?
Hi there. I had this exact same error. When I deactivated the Headspace2 plugin I could edit the page. When I re-activated this plugin the error returned. I then did a clean-up of all the old revisions of my pages with the following SQL query:
DELETE a, b, c
FROM
wp_posts a
LEFT JOIN
wp_term_relationships b
ON (a.ID = b.object_id)
LEFT JOIN
wp_postmeta c
ON (a.ID = c.post_id)
WHERE
a.post_type = ‘revision’;
This fixed the problem! I hopes this helps …
