Hi guys,
In our Xibo ecosystem, we have a user who manages two screens by replacing 8 PDF files every day with the latest updated version. This has been working fine for a while, but for the past two days, one of the files has been throwing up an error when he tries to replace it. The error also comes up if he deletes the file and tries uploading it again from scratch.
The error says: SQLSTATE[21000]: Cardinality violation: 1242 Subquery returns more than 1 row
Is this an issue with the file itsself, or with the server, or is it something completely different?
Thanks for your help!
