this is error my version is 2.6.2
Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8mb4_general_ci,COERCIBLE) for operation 'like' 1267

It seems that there is an issue into the query for the component search view. May be charset issue … It's probably due to the usage and environment.

Can you provide more information about your environment and use case, to be able to reproduce the issue?
Do you have more error details into logs? Can you activate the Joomla ‘Global configuraiton’ / ‘system’ system option ‘debug’ = ‘yes’ and recall this page to have the SQL query text into the error message?

Thank you for this additional information. But unfortunately it's not enough to reproduce the issue.

Can you add, as requested at the top of this topic the information with the 'Report to help BS MyJspace support forum for troubleshooting' from the Backend BS MyJspace Help menu.
Can you add information about use cases: are you using categories, Joomla tags, all the updated options in the general option and for the menu option for the 'pages' view ...?
