Hi，

I have an issue with Database Read/Write (Currently I am using Ignition 8.1.48 trial mode)

Yesterday I was able to delete a row, modify a value even delete a table from Database.

But now the system told me about the database in Read only mode.

 ![1-1](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/c/9cf775c705091b72bf9618872b46a936c460d22a.png)

is it caused by the “Trial mode” and I only can play the write mode for certain period (e.g. 2 hours or xx times)

I have attached some snapshots below for your reference.

Hopefully, someone can give me some clues to get the problem fixed or clarified.

Thanks.

Jian

There’s a button in the toolbar of the Designer to change the comms mode between read only and read write.

Edit: and in the project menu: [Vision Designer Interface | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/ignition-modules/vision/vision-designer-interface#project-menu)
