Hi,
I was able to contact the person who was previously working on the site regarding this issue and here is what he said:
Something is wrong/changed.
Only the pro plugin that you purchased allows to edit multiple events.
And it is disabled.
While I tried to enable it again, it gave me this error.

I have no idea why it went wrong since it was working fine till last week when I left the website alone.
I can provide you a screenshot of the plugin code so that you can contact their support if that can help?
Please help. I have a tremendous amount of work to do with the events and very nervous about what may have happened.
Thanks,
Charmaine
