The plugin needs to be installed in a directory that’s named correctly. At least two of them (
allowedUploads-master) are named incorrectly. I suspect these were downloaded from github using the “Clone or Download” button on github – that’s not the correct place to get the file; you need to get a release package from the “Releases” area (or use the plugin gallery to install the plugin – it’ll take care of this).
I’d suggest deleting any plugins you installed this way, and also checking for entries in the
versions table for them (and removing them if you find any). Then install them from the Plugin Gallery or from the Releases area. Note that OJS 3.0.2 is getting quite old, so I’d strongly suggest upgrading as well. I’m not sure those plugins are even compatible with OJS 3.0.2.
