Afte upgrading to the latest version (7.4.6) the extension gives me the following error:
Warning: Declaration of PlgSystemEmailProtector::loadStylesAndScripts($buffer) should be compatible with RegularLabs\Library\Plugin::loadStylesAndScripts(&$buffer) in /home/xxxxx/public_html/plugins/system/emailprotector/emailprotector.php on line 66
Removing (or reinstalling) the emailprotector extension did not solve the issue, nor did re-installing a fresh download of Extension Manager.
I have also updated the other Regularlabs extensions, did not change anything.
To rule out a temporary issue, like I had before, I restored a backup and tried again, but this time exactly the same happened.
For now, I have again restored the pre-error situation, hoping for a fix.
By the way, my other sites sofar did not have this issue.
