Hi,
I've just updated to the version 5.4.2 and it has an error that blocks edition page. The error is in wp-content/plugins/meta-box/inc/fields/image.php on line 54 and shows: PHP Parse error: syntax error, unexpected ')'. The way to solve it, it's to remove the last comma on previous line.
I confirm the error. The same form me. Exactly the same. However, inspecting the code of the referred file, it seems to be OK.
Can you guys check it out? Since I have several sites it seems the problem will start to cascade on all of them, since every metabox plugin is set to auto update!
Thank you!
EDIT: OH, just saw the last comma on the line #53!
Removing it fix the problem indeed.
It will be fixed in the next update. FYI, the problem might happen with the PHP version lower than 7.4. I'm using PHP 7.4.12 but do not see this error.
