Solution:
To fix these errors in your Opencart 3.0.2.0 store, you can follow these steps:
Step 1: Check the error log
The first step is to identify the specific errors that are occurring. To do this, go to your Opencart admin panel and navigate to System > Maintenance > Error Logs. This will show you a list of recent errors that have occurred on your website. Look for the four errors that you mentioned in the project description.
Step 2: Identify the files causing the errors
Once you have identified the errors, you will need to find the files that are causing them. The error log will show you the file path where the error occurred. For example, the first error mentioned in the project description is occurring in the file /home/drdr3704/public_html/store/storage, so you will need to locate this file on your server.
Step 3: Edit the files
Now that you have identified the files causing the errors, you can proceed to edit them. You can do this by accessing your server through FTP or using the file manager provided by your hosting provider. Once you have opened the file, search for the line of code that is causing the error (in this case, it is `heading_title`). You can then make the necessary changes to fix the error.
Step 4: Upload the edited files
After you have made the necessary changes, you will need to upload the edited files back to your server. Make sure to replace the old files with the new ones.
Step 5: Clear your website cache
Sometimes, errors can occur due to outdated cache files. To make sure that your website is using the updated files, you should clear your website cache. You can do this by going to System > Settings > Edit (your store) > Server, and clicking on the "Clear Cache" button.
Step 6: Test your website
With the errors now fixed, you can test your website to ensure that everything is working properly. If there are no more errors, then congratulations, you have successfully fixed the Opencart errors.
In case the errors still persist, you may need to seek help from an Opencart developer or post your issue on the Opencart forum for further assistance.
That's it for the solution for fixing the Opencart errors. I hope this helps you resolve the issue and improve the performance of your store.
