Martin A.

All good. I have my 997 markers back. 
It took a bit of hacking about, because my best table membermap_markers table was from a pre-IPS 4.2 DB backup. 
Many thanks for everything you do, Martin.

I've seen it is already in the new version : thankyou very much !

Take a backup of the table, then run this query:
UPDATE membermap_markers SET marker_open=1;  

Oh my, that is not good. That is not good at all! Expect a new version in a couple of minutes.
Unless you have a recent DB backup, getting your markers back is unlikely. Unless they're just "soft deleted", in that case your should still see then if you browse the markers.

Not 100% sure if you can "cherry pick" a table from a complete backup. What I would do is import the backup as a new database, then export just the membermap_* tables, which you'll then import to your original database.

That is accidentall hardcoded. Will change that to a translatable string in the next release.

Are you using @Adriano Faria's Club Enhancement? I think that may conflict with this.

Thanks, issue fixed

What's New in Version 1.0.15.1:
Fix - This version restores:
Option to reorder tabs Option to disable features Compatibility:
Compatible with Member Map and with any other resource that adds a tab via hook in the Club. Note:
Tabs added via hook, like Member Map, won't appear in the Manage Features to be reordered. Only tabs created via club will appear in there. Tks to @Martin A.

What part of this isn't working with Rules out of the box?

It's the hook you have on \IPS\Member\Club::nodes(). It's not calling the parent method. 

Didn't know Clubs could have a location, I can add this in the next update. Will not show private clubs, even if you are a member of it.
No, not now. Too much of the code would have to be re-done to achieve this.
You are bringing up the main problem with this yourself, what about those that are in several clubs. I can add a button to Clubs that'll take you to the map, but only show members of that club.

Great, that was it. 

Thanks, saved me quite a bit of thinkering

Create the content in manual PHP mode.
//<?php $embedimage = \IPS\File::get( 'membermap_MarkerStaticMap', $content->embedimage )->url; $return = "<p>{$content->author()->name} checked in at {$content->location} ({$content->_latLngToDMS})</p>"; $return .= "<p><a href='{$content->url()}'><img src='{$embedimage}' alt=''></a></p>"; return $return; Result:

Magic! Thanks 

"&group=calendar" should work. Use the name that appears in the layer list in the map.
I see what's going on. You're hitting the browser storage limit. In Chrome that is 10MB (you can test that here). It is able to save the first 10 cache files, but then the 11th and 12th would push it over the limit. The 13th only just fits. I'll have to explore some other options, or at least see if there's a way to compress the data before storing it.
There you have it, @jair101. 5200 markers is the limit.
@VR6Pete: Sure this isn't happening to you as well?
I'll take a look at this again for one of the upcoming versions. Let me just fix the marker issue first.

Yes, I will update it, and hopefully get it ready before the stable release of 4.2.

Currently on vacation. Not sure why the delete function doesn't work for you. Make sure your members can delete their own content. That's a member group setting. 

Thanks
It looks like this now https://www.walkingfootball.com/membermap/markers/group/2-walking-football-fitness-sessions/

Great news, thanks a lot! So far so good... the first time I accessed the map was quite slow but after 5 minutes, probably caching all the markers again, now it displays instantly! I will keep you updated of any changes  Thanks again!

Impressive! What a productive evening you had

Or early morning  
Just have to make sure it doesn't throw a million error ls the first time after upgrading, but other than that it looks good
