Your theme is probably using somewhere 'addAttributeToFilter'

Something like this:

$collection->addAttributeToFilter('is_saleable', 1, 'left')

Change it to something like:

$collection->addAttributeToFilter('is_saleable', [1], 'left')

Best run search thru your modules and theme files with this addAttributeToFilter

Reference with simillar issue:
