Neatline error in saving record

I've looked through the forums and but it's still not resolved. I get an error in saving record. There's no mod security. Here's the information from Chrome develper tools.

neatline-editor.js:
2 The specified value "!" does not conform to the required format. The format is "#rrggbb" where rr, gg, bb are two-digit hexadecimal numbers.
util.js:
30 RetiredVersion, SensorNotRequired: https://developers.google.com/maps/documentation/javascript/error-messages
kwift.CHROME.min.js:1
Uncaught TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'.

Any help would be appreciated.

Here's some more info - I'm only marginally tech aware but this error message seems significant:

I changed some settings in the neatline underlying map and the records are saving. I encountered a similar mysql error regarding a null column when updating an item...must be something on my host side. However a refresh of the browser (Chrome) resolved that one. I'm not sure what's happening but I think we can close this topic.

Hi pkp3, I'm glad this was worked out. If it pops up again, let us know.
