I can't ungroup objects. This option has been greyed out.
Is there another way?
Look at the objects in the Object Manager docker. That should tell you if the objects are grouped and whether or not they are locked.
Are you sure the objects are in a group? Does it show as a "group of objects" in object manager?
The ungroup option will only be available if the objects are labelled as a group. But you may be able to use the "break apart" operation if you have a single object which consists of several sub-paths.
If that doesn't make sense in your case, it would be best to upload the file so we can check it out. Make a "Save as" copy without a colour profile to reduce the size and if it is under 256Kb you can upload it on the options tab when you reply.
I was able to move some text out from the group then the ungroup all option returned.
strange.
Now it just disappeared on me again!
I checked the Object Manager and is does say "Group of 12 Objects"
Don't see any lock beside it so I guess it is unlocked.
my file is only 85Kb and when I choose it to upload it froze.
How can I upload?
Try copying the file to the desktop first. That will ensure that the file you are choosing for the upload is not already open somewhere.
