When you access to most of the pages in Events Booking backend (for example Events Booking -> Categories or Events Booking -> Events), at the right, there is a menu called Tools which you might need to use in some special cases as explained below:
This tool is usually used when you update from old version of Events Booking to new version but the update process was failure for some reasons (or when you import Events Booking data from a different site - using an older version of Events Booking than the current site). Access to this menu item will help updating database schema to latest version and make sure Events Booking works properly on your site
In case you could not access to Events Booking for some reasons (because SQL error), the tool can be accessed directly via this URL https://domain.com/administrator/index.php?option=com_eventbooking&task=update.update (of course https://domain.com/administrator needs to be replaced with administrator URL of your site)
Events Booking store all of it's URLs in database table called eb_events. These urls are cached URLs, mean urls might still point to old resources in some special case (for example, when you imported Events Booking data from a differnt site to this new site or you created an event with same title in the past, then delete it for some reason and re-create a new event with exactly same title/alias)
That's when you have to Purge URLs so that Events Booking will re-create new URLs and point it to new resource. Access to Tools -> Purge URLs usually help solving these issue
By default, Events Booking only allow sorting and searching registrants for core fields (such as first_name, last_name, email....). If for you want to search for registration records base on data of a custom field, you can use this tool
On a multilingual website, specially when you have many languages installed, the system will need to add more fields to it's database tables to store data for these additional languages and could cause this Row size too large (> 8126) error. When it happens, you can follow the instructions below to get the issue sorted:
Sometime, you might want to change the event thumbnail size for your event. However, change the size (in Events Booking -> Configuration) will only affect thumbnails of new events created from now on
For existing events, normally, you will need to edit the event, save it so that thumbnail for the event will be generated with the new size. That would take much time in case you have many events, and that's why you can use this tool
https://domain.com/administrator/index.php?option=com_eventbooking&task=tool.resize_thumb_images
By default, Events Booking allows you to configure each event to send up to 3 reminders email. If you want to have more reminders, please use this hidden tool:
This requires Events Booking 4.7.0+. And of course, https://domain.com/administrator need to be replaced with administrator URL of your site.
