1. I couldn't even create one single event in the backend, here is the message I get in the frontend calendar view after I did that: "Fatal error: Call to a member function load() on a non-object in ...../joomla/libraries/joomla/user/user.php on line 597".
As many are already using 2.7, this is not a global issue affecting everyone. We can check this directly on your site through a ticket. As we obviously have many tickets and posts at the moment, we're going through as quickly as possible.
2. Also, after I enabled DTRegister EventLink plugin, most all my pages (not related with DTRegister component!) dissapeared and I had to spend one hour figuring out what's going on.
Did you update to the latest version of the plugin? Make sure you are using the plugin from the latest download package.
3. I couldn't figure it out any Template entry, so I can enable/disable different fields based on the template I use.?
Fields used are set per event... on the Fields tab in each event setup... frontend or backend. Your site template has no connection to what fields are used within DT Register. Setup the fields you want for the event. Then when you create another similar event, just COPY the existing event so it will use the same field options.
4. No mini-calendar module? Am I picky to ask for this? Wasn't this one one of the most used module from JEvents?
The mini-calendar module will be coming soon... just didn't make the final cut. Had to get things out and moving ahead. As already discussed in the forum as well as the regular free webinar sessions we've been doing, the module is soon-coming.
5. The calendar doesn't fill all the area in the page? Doesn't it have a fixed width?
The calendar should fill the whole available area. If it doesn't, it's probably related to your template somehow. We could check through a ticket.
6. Locations is shared by all users? Since the users can add events from Frontend, woudn't make sense each user to have it's own locations and to be able to manage them from Frontend?
Locations ARE manageable on the frontend to the users you give permission to. But yes, all locations are shared at this time. Yes, it's true... DT Register is not perfect in every way for every person. If you want to suggest locations to be tied to individual users, that would be a feature request. That goes further than just complaining when it's not there. It's very clear that 2.7 moves much further down the road with frontend access and such. As that is a completely new side of DT Register, it's understandable to put it out there to the level it is... get feedback... then continue to develop based on feedback.
Thanks. We're more than happy to help and working hard to do so. My request is that you just keep your cool. Posts that get ugly will not be kept on the forum as that isn't necessary. We're here to help... not argue with you. Thanks
