[SOLVED] Global Planning is now empty (Blank)

Global Planning was working fine and showing all activities, tickets but now Global planning is showing blank (empty).

Not sure what is going on.   I tried the below which i found in another thread.

I tried both 'utf8mb4_general_ci' and 'utf8_general_ci' for $paramDbCollation in parameters.php:

I am getting the following errors.   


***** ERROR ***** [V10.3.4] Exception-[42000] SQLSTATE[42000]: Syntax error or access violation: 1253 COLLATION 'utf8mb4_general_ci' is not valid for CHARACTER SET 'latin1'


***** ERROR ***** [V10.3.4] Exception-[42000] SQLSTATE[42000]: Syntax error or access violation: 1253 COLLATION 'utf8_general_ci' is not valid for CHARACTER SET 'latin1'

Any ideas?
 

What is the default ?   What is recommended for this parameter?

Suggestion to use $paramDbCollation = 'latin1_general_ci' resolved the issue.

Thank you
