after a login to OJS back end i have notice when i click
website on Setting then on Plugins tab the installed plugins dont display but the section keeps on loading.
See attached image
I have checked PHP error log and noticed this error
[09-Mar-2018 12:15:01 UTC] PHP Strict Standards: Declaration of CustomBlockPlugin::getSeq() should be compatible with BlockPlugin::getSeq($contextId = NULL) in /public_html/plugins/generic/customBlockManager/CustomBlockPlugin.inc.php on line 0
How do i resolve this installed plugins
Kind Request
