For example, suppose you receive the warning “Parse error: syntax error, unexpected ” in /home/your-username/public html/wp-content/themes/yourtheme/functions.php on line 50.” This indicates that line 50 of the functions.php file of the “yourtheme” theme contains a syntax problem.

1. You would first need to access the  functions.php file of your theme. You can do this using the file manager in your hosting account or an FTP program like FileZilla.
2. You should create a backup copy of the functions.php file before making any changes. In this way, you may always restore the original file if something goes wrong.
3. Using a text editor like Notepad++ or Sublime Text, open the functions.php file. Find line 50; this is the line that should be generating the issue.
4. Look over line 50 of the code and try to spot the issue. The error in this instance is an unexpected “{” This could indicate that a function or class was not closed properly, or that there is a missing closing bracket or semicolon before this line.
5. Make the necessary adjustments to correct the mistake once you have identified it. You would include the missing closing bracket, for instance, if that were the error. If a semicolon is absent, you would add it.
6. The functions.php file should be saved before being reuploaded to the server and replacing the old file.
7. To check if the error has been fixed, reload the webpage. If you use a caching plugin or your browser has a cache, clear it. [clearing cache in WordPress]
