DragonByte Tech:
This means you have changed the collation of certain DB tables but not your entire database, you will need to make sure all DBTech tables and their columns have the same collation as your vB tables.

can you tell me How to change DB tables ? please
DragonByte Tech:
You should contact your host for instructions on how to change collation if you don't know how to do this yourself.

My server staff says:
let me know your exact db table and db name and the collation format you want to keep, I will check and try to do it,
Help please i think DBTech is busy i really need help
