Greetings all:
I having the same issue that was occurring in another archived post that was never answered. The link to that archived post is: APEX Page is not saved even after successful save message is displayed
I am using the following version of APEX:
| Product Build | 5.1.0.00.45 |
I'm using the following database version:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
I am using the Universal Theme in an application that was converted from 4.2, which was using a legacy theme. The conversion was several months ago, and was successful. Now I am attempting to modify this saMe application, and I'm having the following issues...
After building a new APEX page with one region (an interactive report), I saved the page successfully, then went back to this same page the next day. I made a few changes to the page and pressed the "Save" button and got the following message:

When I went to navigate away from this page, I get the following message:

It doesn't matter how many times I hit the "Save" button, my code will not save.
My co-worker is having the exact same issues when she was attempting to modify some JavaScript code in one of her pages in another application, so this does not happen within just one application.
Has anyone experienced this before? Is there a solution?
Thanks,
Stan
