Development environment bug?

On a single record form, under
Form Settings
Edit fields
I change the Label for fields. I click the save application button. The changes are not saved. I don’t see any error message. Could I be running out of memory. There are about 200 fields on this form. I can go into the Fields “folder” below and change each label, and it sticks, but it is much slower.

Automatic or manual SC installation?

I install and do all updates automatic.

Just for try. Increase max_input_vars un php.ini to a higher value

Thank you! Thank you!
This seems to have fixed my issue. In addition, it seems to have significantly sped up the development interface for me. Saving changes to a field and clicking on another field to edit has gone from 15 seconds down to seconds.

…post above should say “down to 7 seconds”
