OJS refusal to load installed Plugins at backend

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

installed_plugin
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

Hi @Simon_Muchemi,

That’s a warning and it shouldn’t cause OJS to stop running. Check further up in the log, looking in particular for anything containing the word “error”.
