Since latest updates (starting from 1.4.2) when I access the "whitelist" and try to create new or edit existing entry I get error message:
Call to a member function getKeyName() on bool

bfstop 1.4.1 + Joomla 3.9.25 = works
bfstop 1.4.2 + Joomla 3.9.25 = doesn't work
bfstop 1.4.3 + Joomla 3.9.25 = doesn't work
bfstop 1.4.3 + Joomla 3.9.26 = doesn't work

Re-installing 1.4.1 after upgrading to 1.4.3 (using Joomla uploader without removing newer version first) breaks the whole site and extension files need to be deleted manually from server.
Error message:
1146 Table 'db-redacted.#__bfstop_whitelist' doesn't exist
