Error in query:
 ('SELECT `value` FROM `tabSingles` WHERE `doctype`=%(param1)s AND `field`=%(param2)s', {'param1': 'System Settings', 'param2': 'enable_scheduler'})

I am facing the same warning, have you resolved it?

Any solution on that

Check if the enable_scheduler field exists in the tabSingles table:

SELECT value FROM tabSingles WHERE doctype = ‘System Settings’ AND field = ‘enable_scheduler’;

If no result is returned, manually insert the missing field:

INSERT INTO tabSingles (doctype, field, value) VALUES (‘System Settings’, ‘enable_scheduler’, ‘1’);

ERROR 1146 (42S02): Table ‘_d2d7bb93fa6bee5f.tabSingles’ doesn’t exist

That also not work they show error.
