Error 500 accessing the User Manager

[pietdv]

Since my upgrade from 1.7 to 2.5.3 I've got problems with contacts and the User Manager. Unable to send email via the contact form. When I try to access the User Manager I get the following error message.

500 - An error has occurred.
Table 'pietsweb.j17_user_notes' doesn't exist SQL=SELECT n.user_id, COUNT(n.id) As note_count FROM j17_user_notes AS n WHERE n.user_id IN (a whole string of numbers follows on)

I've deleted both my single contact and single contact category but still the same message. I am running joomla! 2.5.3 locally on my laptop while working on the site. This may have a little to do with the non sending of mail, however the User Manager is not a happening thing!

Any offers of help appreciated.


All the best,

I had this same problem but still using 1.7. I looked at extension manager > databases and had the message that my databases were not up to date. Simple using the update button has fixed the problem for me.
Hope this helps
