Hi Alexei,
Reviewing the source code in dbPageSettings.cs I see a probable cause.
The CompiledMeta param is declared as Blob instead of Text in the create and Update Method
I am changing it in my copy from this:
arParams[29] = new MySqlParameter("?CompiledMeta", MySqlDbType.Blob);
arParams[29].Direction = ParameterDirection.Input;
arParams[29].Value = compiledMeta;
to this:
arParams[29] = new MySqlParameter("?CompiledMeta", MySqlDbType.Text);
arParams[29].Direction = ParameterDirection.Input;
arParams[29].Value = compiledMeta;
Can you try that solution?
Hope that helps,
Joe
