When attempting to add new records of any kind, accounts, employees, etc, it fails with message: "Error: There is no active transaction." This is a brand new installation on a CentOS server with everything but LDAP in passing proper configuration checks.
CRON Jobs active?
All defaults say 'Active' inside Yeti except Backup.
look like this (last scan started/ended recently or at installation time?)

Thank you. I am lacking in knowledge of creating CRON jobs actually. Do I create 2 CRON jobs total? One for the vtigercron.sh and one for the cron.log file? Should both jobs run at */5**?
Also, I don't see the cron.log file. Do I just create a text file called 'cron.log' and put it in /cache/logs/cron.log?
Also, in the vtigercron.sh am I required to set the VTIGERCRM_ROOTDIR or leave as-is? Thanks.
CRON has nothing to do with adding records. If you are not able to add records then you have to check the logs to see what’s wrong.
@masterGH If your Question is for Schedule task in Crontab, you only need to add this line.
*/5 * * * * sh /var/www/crm/cron/vtigercron.sh
This path /var/www/crm/cache/logs/cron.log is That's where it's stored logs.
If you whant know how to use Crontab see this information

Example
min hour day/month month day/week Execution time
30 0 1 1,6,12 * — 00:30 Hrs on 1st of Jan, June & Dec.
0 20 * 10 1-5 –8.00 PM every weekday (Mon-Fri) only in Oct.
0 0 1,10,15 * * — midnight on 1st ,10th & 15th of month
5,10 0 10 * 1 — At 12.05,12.10 every Monday & on 10th of every month
Go to Database and use this query
SET GLOBAL sql_mode='';
@ahmido That works! Thank you sir. However, just fyi, you will lose the global change when you restart the MySQL server, so you should add: sql_mode="" to your my.cnf file under [mysqld] for permanent changes. You can also do it temporarily your way or through PHPMyAdmin in the Variables section.
@skramanzia Thanks for the explanation on CRON jobs. I had done some research right before you posted that and saw the same diagram. I do understand more about them now. Thank you.
@paula-w Which logs should I have checked? Thanks for your help. Checking the log interface inside Yeti showed nothing. The solution was @ahmido 's above with a slight modification noted in this post (see first section of this post.)
