Apologies, I haven't read the entire thread, so if anybody else has already post this, please delete it.
I just recently discover (a possible bug) actually, to be precise, a conflict between Simple Portal (Recent Topic) Block and Event Registration.
What is happening is that if you make an Event where people are required to register and/or confirm their participation to such event, and in the same page you have the Simple Portal Recent Topic block displayed, the page just stop loading at the heading of the Recent Topic block.
Interesting enough it doesn't conflict with the other (very similar block) Recent Post.
If I disable the "Recent Topic" block completely or only from any page/s where the Event registration form is displayed then everything works as usual.
Running SMF 2.0.11, SP 2.3.6, Event Registration Mod 2.26, Event reminder Mod 2.31
It would be interesting to know if anybody else is able to reproduce the same issue...
Thank you HoverClub
for this excellent mod.
