When you forget to uncheck the "RegExp" button in the "find and replace" dialog, and it's too late to undo your changes.

I just mistakenly replaced 48 hours of work with the old files... I think i'm gonna die. Someone please help me if you can.

TL Dr :- Debugging a software I barely know about was slow and ended up breaking in the shop it was used in and reverting the changes does not solve the problem

I asked my father a few days ago why he was buying a dedicated server for his ERP software and not using a client computer as his server which he is doing in his shop currently. He said that it was slow on other computers in the LAN which is an wired. The solutions given by the company that made it did not work. Big bills would sometimes also dissapear which took around 30 minutes to make. So when he bought the computer to home during lockdown I pulled up the debugging guide from the company which summed up to check latency,ram and add these files to exclusion list of your antivirus. Latency was kinda high at the first when pinging another computer on the LAN but I was testing on WiFi so it could be pretty inaccurate. The computer met the ram requirements so that was not a problem. I checked the data path by opening the software and accidentally typed something but I did not worry since the changes needed to be manually accepted. I added the files to the Windows defender exclusion list and shut it down.

Next day :- My father calls me up and says the software is working on the server but is broken on other computers. So I check if the changes were automatically accepted for some reason and yes that happened. So so pull up a guide to configure the software in multi user mode and I replace the mistyped setting with the correct one and it still does not work. My father asks me to undo everything by using anydesk. I remove all the exclusions I added to Windows defender and disable windows firewall. Still does not work. Restart the computer and software. Still does not work. Check permissions on data folder. They are correct.

WTF I reverted all the changes I made and the software does not work on other computers.
