Problem After Upgrade to V3.2.12

Read 52 times
I have been using Centovacast V3.2.10 software since 2017 and decided to upgrade it to V3.2.12. Hoping that the new version is stable. After completing the upgrade, the accounts that has a AutoDJ has stopped working.

When I start the server, it returns an error:
At ../hoperadi/etc/liquidsoap/centovacast.liq,
line 131, char 8-9:this value has typeref(string) (inferred at ../hoperadi/etc/liquidsoap/centovacast.liq, line 128, char 9-14)but
it should be a subtype of (the type of the value at ../hoperadi/etc/liquidsoap/centovacast.liq, line 131, char 8-26)ref((default:_)->_)
Log has not been created, which may indicate a permissions problem or an inability to run the external application. Consult the Centova Cast
knowledge base.

My question is,
1. How to fix this issue?
2. Is it possible to undo the upgrade?

Any help would be appreciated.
