I have reviewed all files and directories: are in place and have not changed their codes.
The same problem has appeared when upgrading to 2.2.1 with the image of custom_logo, so now I see with the avatar (image) of the user's profile: do not see what they are uploaded, or are new to upload. The action of the image is made up (it's in the "/content", but not seen on the web).
The same is happening with the icon of the course. The icons up "properties" are not seen (I reviewed yes uploaded to the server in "/images/content"), except those ".jpg" that are preset in the "/images/courses".
Now, unexpectedly, the problem is with the database. For example, when the instructor wants to send a message to a registered student alert appears:
"ATutor was unable to access the database. If the problem Persists, Please report this to an Administrator With This reference date ..."
And the last problem is that when accessed by a "teacher" or "student" comes the warning:
[b]"ATutor was unable to access the database. If the problem Persists, Please report this to an Administrator With This reference date ..."[/b]
Previously all I've done as an administrator is: 1) to create a user account that has confirmed your email, 2) has requested to be enrolled in a course, 3) the instructor has approved and thereafter; then: [b]"ATutor was unable to access the database If the. Persists problem, Please report this to an Administrator With This reference date ... "[/b]
Is there any way to fix this? If it is raparar or optimize the "database", where it is housed? because I can not find it anywhere on my server.
I consult: will need to upload everything again begun LCMS and content from a new installation?
