Updated all other facets of website including fancy product rest api plugin, fancy product designer plus,WP, etc
Then installed the newest version of FPD ver 4.2.2 released on Dec 22.
Immediately got the wp message about a fatal error for the website. I had to revert to the prior version of fpd in order to bring the site back.
Checked the error log and found the following message (repeated several times within a very short span probably from our trying to bring the site back):
[07-Jan-2020 01:01:49 UTC] PHP Fatal error: require_once(): Failed opening required '/home/im20pactgraph17/public_html/wp-content/plugins/fancy-product-designer/admin/wp_autoupdate.php' (include_path='.:/opt/cpanel/ea-php73/root/usr/share/pear') in /home/im20pactgraph17/public_html/wp-content/plugins/fancy-product-designer-plus/fancy-product-designer-plus.php on line 62
Perhaps someone has a thought on this?
