Brilliant! thanks so much for fixing this Patrick, as usual you are a star.

Fixed it sort of

class-maps.php

I added the following two lines in the L.tileLayer sections just above }).addTo(thisMap);

maxNativeZoom: 18,
maxZoom: 20,

It’s not perfect as it won’t work with the Hydda maps mainly because for some reason despite having maxNativeZoom set to 18 it’s still loading one level higher, fortunately thats fine for me

I also changed the mouse scroll zoom from 0.25 to 1 just so I don’t get the 5 showing under the zoom control box when it’s .25 or .75

With regard to zoom it seems to vary and yes it will depend on the maximum file resolution so using the test here https://plnkr.co/edit/z1p9x05vAv4h1sJJrDQC?p=preview which uses the standard open streetmaps tiles I can use a maximum value of 19 for the MaxNativeZoom setting and zoom up to 35X but if I change MaxNativeZoom to 18 it will only allow me to zoom to 33x although that seems to vary slightly, I’m not worried about silly zoom levels where everything is out of focus anyway it was more curiosity as to how it worked.

That I have worked out, everywhere is tiled, the larger the magnification the smaller area each tile covers, thus the different folders, once you reach the maximum magnification for the folders then it will still let you go up but it does so by just scaling the highest resolution image it has. So I understand how it works but I still can’t write the code to make it work LOL

Sorry Patrick you misunderstood, or maybe I didn’t explain it well, I meant the maximum zoom possible with leaflet is something near 36 but in practical terms anything higher than 22 is silly, not that your plugin goes up to 22, I was experimenting with the code on the https://plnkr.co/edit/z1p9x05vAv4h1sJJrDQC?p=preview site earlier trying to understand the issue

I only found out about MaxNativeZoom when I was trying to find out why I was having problems and using google search, I agree it’s not easy to find in the docs but it’s here https://leafletjs.com/reference-1.5.0.html#gridlayer though it’s not a very easy to understand explanation.

This is not meant as a moan I really like your plugin, I was just trying to work out why I was getting the grey screens, I’m not a programmer, I can just about manage a bit of CSS and if someone like yourself points me in the right direction I can almost understand PHP, js is beyond me though, I am fairly good at finding faults and working out why they are likely to be occurring, I have a good analytical brain, what I don’t understand is why only a few people are seeing this issue, that’s why I tried installing on a plain old boring site with no extra code, I figured if it was the site then I would get a different result but I didn’t, I also tried several browsers Chrome(my default) firefox, edge and even i.e because I know that sometimes Browsers can make a difference. So I then tried to work out what was going on, I used chrome developer tools to see what was loading and when and discovered that none of the map tiles load until after I drop under 18x magnification, then I looked at other sample sites and worked out that for some reason your plugin appears to be loading the map tiles at the wrong magnification. i.e loading the 18 magnification tiles when zoom is set to 17, so I then wrote everything up, because in the past you have been so helpful and I wanted to try and work out why it was not working for me as it should.

Anyway it wasn’t meant detrimentally I think it’s a brilliant plugin I just want to get it to work for me

Tried without elementor, with default formatting and twenty twelve theme still get grey screens at top two zoom factors (18 & 19)

Note I appear to not be the only person with this issue as reported earlier in this thread by iamthewebb

By the way I should mention that the high magnification maps don’t appear in the backend either, sorry that’s probably important, in the previous release they went up to 18x but went grey at 19x is there something you altered in this version that might have an effect there ?

I have no idea if this is the problem but I saw somewhere (and can’t find it now) that maxNativeZoom: might be important, apparently it won’t display higher than whatever you have that set to

Pretty certain thats not the issue but I’ve just disabled it you can reload and see
