Hi Andras,
Thank you for your reply. I removed the two caching plugins from the mu-plugins directory as instructed: “endurance-browser-cache.php”, “endurance-page-cache.php”
Unfortunately this has not resolved the problem. Please advise.
UPDATE:
Another observation/symptom with this issue is that this does not occur when logged into the wp-admin console…but when logged out (general public website visitors) the issue prevails.
