Thanks for the reply.
– deactivating ALL (yes all) plugins temporarily to see
– switching to the unedited default Twenty Fifteen theme for a moment
Tried that, it did not resolve the problem.
– If all the above steps do not resolve the issue, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory
Doesn’t help either, I always update manually.
