Community Q&A
How do I fix a WordPress parse error?
Identify the file causing the error via the error message, then use FTP or a file manager to correct the syntax or temporarily rename the file to disable it.
Can an outdated PHP version cause syntax errors?
Yes, using an unsupported PHP version can cause parse errors if your plugins or themes use newer PHP syntax that the server cannot interpret.
How do I disable a plugin if I cannot access the dashboard?
Access your site via FTP or hosting file manager and rename the specific plugin folder inside wp-content/plugins to disable it immediately.
What should I do before editing theme files?
Always create a full backup of your website files and database before making any changes to functions.php or other core theme files.
