Do I understand you correctly that your map image isn’t shown completely but only partially? That might be due to your server configuration.
Could you please check in Site Health (under Tools) and there on the second tab (Info) the following values:
Under “Server”:
– PHP post max size: should be 10MB or higher
– Upload max filesize: should be 10MB or higher
Under “WordPress constants”:
– WP_MEMORY_LIMIT: should be 10MB or higher
– WP_MAX_MEMORY_LIMIT: should be 10MB or higher
Plus, if you have a web application firewall on your server (e.g mod_security), than it should also be configured in a way that it allows requests of 10MB or higher. This doesn’t show up in Site Health, so you might want to check with your hosting provider or the firewall backend.
Reason: Retina versions of big images have file sizes of multiple MBs (usually not higher than 5 but lets say 10MB, to be on the safe side). Maybe there is a lower limit on your server, so images might get cut off.
Does this help?
Thanks for the swift reply. I checked my Site Health and all values are way higher than 10MB.
However the hint with mod_security way perfect, I had a limit of 2.5MB configured on my server. Increased that to 10 and now the big map images work, too. Thanks for the support!
