OJS 126.96.36.199-13 Material Theme version 188.8.131.52
When switching between themes we have started receiving the following error message:
Notice : Trying to access array offset on value of type null in /home/radjr1/domains/ojs2.wmpllc.org/public_html/ojs/plugins/themes/material/MaterialThemePlugin.inc.php on line 173
It seems to reference a home page image. If we remove all images, the system seems to have some persistence and even though the “Save” completes without error, The image that was deleted re-appears in the image selection box. Clearing template/data caches don’t make any difference.
Seems the Homepage Image file is not overwritten properly.
