Here is an example of the only way I know of to fix when this error occurs:
select * from lm_sendq limit 1;
output from that command:
+----------------------------------+--------+---------+-------+--------+-----+------+
| id | bat | battype | mtype | uid | mid | xtra |
+----------------------------------+--------+---------+-------+--------+-----+------+
| 604346a728bd63f014f5c53b3501bfc0 | f7361a | 1 | 1 | 102254 | 227 | |
+----------------------------------+--------+---------+-------+--------+-----+------+
1 row in set (0.00 sec)
next command:
delete from lm_sendq where id="604346a728bd63f014f5c53b3501bfc0";
However, this ID does not exist in the lm_users table so we are still not sure why it is occurring?
Any help, fix or whatever would be greatly appreciated!
