you can see screenshot in attachment. What about URLS when install older version? Please help.

Denis

For URLs just follow the instructions from my original answer:


Of course don't forget to make a current backup of your website (eg. with Akeeba Backup) before doing this.

But you said that in JoomSEF 3 configuration is located in jos_components table in the params column. The main JoomSEF record has parent=0 and option=com_sef values. There is no configuration.php. How to restore configuration in joomSEF 3?

Better solution for me is to fix bug in upgraded joomSEF that does not show bottom part of URLs Manager page. Do you have any idea how to fix it? I send screenshot so you can see it. Please help.

Yes, URLs and all their data are stored in jos_sef... tables and JoomSEF Configuration is stored in jos_components table in the params column.

The pagination should be displayed correctly. Try enabling error reporting on your server or check your server error logs to see if there's any PHP error reported.

when switch to display errors I can see errors.. see screenshot in attachment

The error message is usually caused by a corrupted table in your database, so it seems that jos_sefurls table got corrupted somehow.
You should backup your database and then try running the following SQL using phpMyAdmin or similar tool:

MySQL documentation recommends running the repair SQL twice. For more information: dev.mysql.com/doc/refman/5.1/en/repair-table.html
You could also try asking your web hosting company to check the database for you.
