Hi, I recently updated our Paper server from 1.21.7 to 1.21.11 and version 2.10.0 of FancyHolograms via Modrinth, and I'm now getting this error in the console when starting the server. The holograms I had before the update are no longer visible in our world. Is this a known issue & is there a fix for it? Would an older version of the plugin possibly
still work?

i'm not entirely sure how to do that - i have a server through a hosting service and have never touched the java version there

#

we're on paper 1.21.11

#

I am using hosting too , they have pannel that I can choose which version on java to use for the server

#

Maybe the hosting dosnt offer change java version

upbeat raptor
#

i don't think so

graceful coyote
#

hmm they control the start file of the server and java version on the machine running the server i guess

#

Maybe contact support and ask them can you update the java from 21 to 25

i had one other plugin that didn't work and downgrading to an older version of the plugin worked for me, so i might try that with this one as well

#

or you just can go back to older version like me

#

the new updates go to java 25 and thats the reason not starting

upbeat raptor
#
