Moodle 3.1.4
I added an image (using the TinyMCE editor) within an HTML block and it appeared just as it should...until a day or so later. It disappeared and when I select the edit icon to configure the block, I received this error: Cannot read file. Either the file does not exist or there is a permission problem.
Within the same course, I had added a SCORM package. Again, it worked fine initially, now it won't load and when I try to edit the settings, I'm greeted with this message: Cannot read file. Either the file does not exist or there is a permission problem.
Those are the only two elements in the course. Any advice? Thanks so much.
