Hi, in one site with GeneratePress installed it started to appear this error after an automatic WordPress update (to 5.4.2):
Notice: Undefined index: gp_social_hook in /home/xxx/public_html/wp-content/plugins/gp-social-share-svg/gp-social-share.php on line 22
Warning: require_once(/home/xxx/public_html/wp-content/plugins/gp-social-share-svg/inc/metabox/meta-box-group/group-field.php): failed to open stream: No such file or directory in /home/xxx/public_html/wp-content/plugins/gp-social-share-svg/inc/metabox/meta-box-group/meta-box-group.php on line 38
Fatal error: require_once(): Failed opening required ‘/home/xxx/public_html/wp-content/plugins/gp-social-share-svg/inc/metabox/meta-box-group/group-field.php’ (include_path=’.:/opt/cpanel/ea-php73/root/usr/share/pear’) in /home/xxx/public_html/wp-content/plugins/gp-social-share-svg/inc/metabox/meta-box-group/meta-box-group.php on line 38
I had to enter using FTP and delete the plugin.
Thanks,
Francisco
