Error 1166 Incorrect column name in Administrator

When i try to open the Membership Pro component from my Joomla administration i receive a white page with the following message.

Error
An error has occurred.
1166 Incorrect column name '' SQL=ALTER TABLE `xbhm9_osmembership_plans` ADD `` VARCHAR( 255 );
Return to Control Panel

That's strange. Maybe the installation was not completed for some reasons and it causes the issue. Please submit a support ticket sending us super admin account of your site so that I can check and correct it for you

ok, i sent it.

the installation was working fine for more than a month that i use this component. This happened suddenly.

Really strange. My dev just checked it and didn't see the issue anymore. Could you check it again ?
