I'm running Moodle 3.4 with solutionsheet plugin version 3.3.0 and I have problem with newly uploaded solution sheets. They are not displayed to my students and it throws this error:
Debug info:
Error code: filenotfound
Stack trace:
line 482 of /lib/setuplib.php: moodle_exception thrown
line 1881 of /lib/filelib.php: call to print_error()
line 4800 of /lib/filelib.php: call to send_file_not_found()
line 40 of /pluginfile.php: call to file_pluginfile()
The oldest assignments with solutions sheet are displayed correctly, so I do not know, where the problem is.
