Markers do not show on Joomla 3
It looks like entries markers aren't loaded on Joomla 3, there also appear following notice there:
Notice: json://{"section":"add_css_file","message":"File /home/sikorasobipro/test4.sikora.sobipro.eu/components/com_sobipro/usr/templates/default7/css/geomap-module.css does not exist.","code":0,"file":"SPHeader","line":616,"content":"In file SPHeader at line 616"} in /home/sikorasobipro/test4.sikora.sobipro.eu/components/com_sobipro/lib/sobi.php on line 107
On Joomla 4 everything seems to be OK. Tested on Joomla! 3.10.6; SobiPro 2.0.0.43 RC; SobiPro SP-GeoMap 3.0.0.2 Beta; SP-GeoMap Field 4.0.0.3 Beta
