hi

during setup process, I have a red cross on class-video plugin.
There is no warning in installation log and the plugin is the list of avaliable plugin.

is there a trouble somewhere ?

Not that we know about. Without any error it will be hard to find out. Best look if it occurs again.

Some kind of error occurred when the class video plugin was initialized during the setup process. The red X is in fact the warning that this happened.

There should be an error listed in some log somewhere, though. Without the error message we cannot tell if there is a general issue.

The red X happens when the script does not return an image (the checkmark.) That will happen only if the script does not complete correctly.

unfortunatly, I can't see any error anywhere on my server.
but I did 3 updates, and everytime I had this redcross on class-video plugin.

It may also be that the script does not complete "in time" for the browser. Look in the setup log for entries for the class video plugin. There should be the following:

Plugin:class-video setup started
Plugin:class-video option interface instantiated
Plugin:class-video enabled (9 | CLASS_PLUGIN)
Plugin:class-video setup completed

If all these lines are present then nothing went wrong, just the image did not get back to the browser quickly enough.

I don't have any of these lines in my installation log.

This means that for some reason the "fetch" on `[Image: http://localhost/test_sites/dev/zp-core/...lass-video]`
did not work. Why that would be I cannot say, the same form is used for all the plugins. But maybe try entering the link (without the img src) and see what you get.

{edit} of course change `localhost` to whatever it should be for your install.
