What is the correct way to modify code with ocmod?

Question

opencart

Greetings!
Done in opencart:

• Uploaded the xml using addon install manager
  
• In the add-ons manager, I completed the update and received a response that "The list of OCMOD add-ons has been successfully updated!"
  
• Updated the page on which it was planned to perform the correction
  

As a result, there were no updates. How to correct correctly or see what exactly I did wrong?

Answer 1

OCMOD searches the files for a string and, based on the results of this search, makes changes.
The problem is most likely that the file that needs to be changed does not have this text or it is different.
How to fix:
1. In ocmod, fix the searched line
2. Manually fix the necessary files
