Fields dissapear in Designer after save

CF 5 with Joomla 3.6.5, on shared Godaddy.

I've been working on my new form since yesterday. On save, fields just disappear in Designer.
Website will sometimes go down for a minute after save as well.
Nothing out of the ordinary, just a simple form, 10-12 fields sent by email.
Have to re-construct form and pray. Since last night this has happened on avg. 3 out of 5 times.

Form does process well online on tests.

Help !!

Hi fdamours,

Are you able to increase the max post vars setting in your PHP config ? that would solve the issue.

Best regards,
Max

Yes, let me try .....

hum ....

- created a copy of my form,
- removed dbsave event and saved > site crashed.
- when back up after a minute or so, I renamed a field in my copy,
- clicked save, process stuck.
- after a minute, I opened under firefox, maybe changes have been saved, but no.
- i updated the same field in firefox, worked well
- then bugged again in firefox I can only make on edit and save.
- 2 out 3 time after, site crashes

php.ini settings

upload_max_filesize = 10M
post_max_size = 20M

Additional info on error

FROM '#_session' WHERE 'time'< ''"

Hi fdamours,

Please see this FAQ

Thanks for all your help

Shared hosting resources on godaddy has difficulties supporting form update requests on server. Tried a few things with provider rep. php.ini settings and all.

I counted characters in one form update query and it's in the 30k char range.

Finally decided to install a website/database copy locally on wamp, and export/update chronoform table contents from dev to prod. Locally, I can manage my forms at least.
