Hi Philippe!

Have you tried clearing the cache?

The error you’re getting is probably related to the type hinting within Fluid’s AbstractCompiledTemplate class. It was added only recently and would probably not have been part of your compiled templates in 13.2.x. Clearing the cache will generate the templates again and they should start working.

Hi,

Thanks,

after the stress of the blank screen, I made database check, upgrade wizard and flush cache and all was OK.

my installation is with old introduction package and bootstrap ; I am waiting for 13LTS (indexed search not working anymore here)

That’s excellent news! Glad to hear you figured it out. :grinning:
