extension manager not populated

[lshore]

I recently moved a contao site from a local host to my isp. I ftp'd the directory structure to the isp site then used phpadmin to retore the database. The site is behaving properly but when I open Extension Manager - no extensions are shown. I have tried updating the database from extension manager and using install.php.

The 'tl_repository_installs' (mysql) table appears to be empty while the 'tl_repository_instfiles' table is populated ok. Have I missed a configuration step?

Just attempted to update via install.php again and now see the following:
The database is not up to date!

Please note that the update assistant has only been tested with MySQL and MySQLi drivers. If you are using a different database (e.g. Oracle), you might have to install or update your database manually. In this case, please go to system/modules and search all its subfolders for config/database.sql files.

Change existing columns
	Select all
ALTER TABLE `tl_module` CHANGE `box_column` `box_column` varchar(100) NULL default '';
ALTER TABLE `tl_module` CHANGE `defaultContent_column` `defaultContent_column` varchar(100) NULL default '';
ALTER TABLE `tl_module` CHANGE `defaultContent_css_class` `defaultContent_css_class` varchar(100) NULL default '';
ALTER TABLE `tl_boxes` CHANGE `title` `title` varchar(255) NULL default '';
ALTER TABLE `tl_boxes` CHANGE `headline` `headline` varchar(255) NULL default '';
ALTER TABLE `tl_calendar_events` CHANGE `tt_bg_color` `tt_bg_color` varchar(6) NULL default '';
ALTER TABLE `tl_calendar_events` CHANGE `tt_fg_color` `tt_fg_color` varchar(6) NULL default '';

This occurs repeatedly - Not sure where to try next.

Did you try to fill the empty table with the content from the previous host. It shouldn't be empty there...

Thanks for the reply
Further checks indicated that there may be some corruption or invalid field types - possibly due to some legacy outdated extensions. ( Boxes and Calendar Events look like the likely suspects) I'll set up a copy on my local server and try your suggestion updating a few records at a time to try and isolate the problem.

Thanks again
