Thank you so much for responding quickly :)
The site is londonjazz.net. You will see that the Categories link under Events is broken.
My permalinks slugs all correspond to the slugs in the main Page settings.
While testing this what I noticed are these:
1/ when the events manager is installed, the following pages are created automatically.
Events is at the top level, Categories, Locations, My Bookings are under Events.
2/ When I look at the Events > Settings > Pages > Permalink Slugs, the original set-up is:
Locations: locations (NOT events/locations)
Event Categories: events/categories
Event Tags: events/tags
3/ These sub menu links broke after I made some changes to Location page format (or it could have been a single event page). I had made most of the changes before I inserted all the events data and at that point the links were still working, but after I put all the events, I wanted to do a bit of cosmetic changes, it broke again. I remember previously, it happened after all the location data were added and I made some mods to the format. Could having a lot of data affect it anyhow???
4/ At this point, the links to both Categories and Locations were broken (and I realise it now that link to Tags is broken too).
5/ When I manually changed the Locations slug (originally it was /locations) to what it is supposed to, i.e. /events/locations, the Locations link started working again.
6/ The other two (Categories, Tags) slugs are correct from the beginning so I could not change there. If I manually change it to /categories just to see what happens, it redirect to /events/categories, etc anyway.
7/ I also noticed that, without changing the Categories slugs setting in EM > settings > pages > permalink slugs page (i.e. keeping /events/categories as it is), but if I just put Categories page in the Pages setting in the main menu to the top level (i.e. so Event and Categories come to the same level). The link still works.
8/ I did another test - I created a new page say, 'event categories' and in the text field, I put [categories_list hide_empty=0] and save. If I put this page under Event page, I get the same error. If I put it at the top level, it shows categories list as expected.
A couple of things to note about my site settings:
- I am not using bookings and so I put My Bookings page in the trash so that it won't show up in the menu.
- I use 1 attribute for Events and 2 for Locations.
thanks for your help in advance.
