Hopefully it helps!

perhaps it would be better to contact your webhost & request to disable that strict mode
you may also try below method but not sure it would work
uninstall the plugin.
open the plugin file mytabs.php with notepad++ or editor at webhost panel
around line 116 find
$db->add_column('users', 'default_tab', 'TEXT NOT NULL');
change to
$db->add_column('users', 'default_tab', 'TEXT NOT NULL DEFAULT 0');
save the file & try using it
btw, this MyTabs plugin was NOT coded in a perfect manner. better to not use it.
