After upgrading JoomSEF I've receved error: Could not save the SEF URL to database: Unknown column 'Itemid' in field list. So I decided to disable JoomSEF and to use defaut joomla SEF, but it works only if I absolutely disable JoomSEF. In than decision I will lose all SEF urls created JoomSEF previously. How can I resolv it?

Hello,

What version of JoomSEF have you used before upgrading and what version do you have now?

Best regards,

Hello!
First time I setuped JoomSEF about 1,5 year ago, second time - about one month. And now I have latest version.

And do you use JoomSEF 2.x or 3.x? And what version of Joomla do you use - 1.0.x or 1.5.x? Have you used our automatic upgrade function to upgrade your JoomSEF?

Best regards,

Version of my Joomla is 1.5.x and latest JoomSEF 3.7.2

This is very strange, your database must have got corrupted somehow. You will probably need to uninstall JoomSEF and install it again. If you don't want to lose your URLs, export them first using the Manage SEF URLs page, and import them again after the new installation.
Or we can try to fix the database first if you want - in that case, use some MySQL manager (phpMyAdmin for example), find the jos_sefurls table in your database and post its structure (field names and types).
