Let’s see why the connection between the LR plugin and the WP plugin is not working. Please check every item of this list carefully. This covers 99.8% of the issues.
The WordPress API needs the .htaccess to work. Sometimes, WordPress doesn’t do it magically and you need to trigger it. Check your Permalink Settings (/wp-admin/options-permalink.php), check Post Name (as long as it is not Plain), Save Changes. Do what described in the first paragraph again. Does it work better? It is a good practice to use permalinks. If you don’t want to use those permalinks for some reason, check this: StackOverflow.
– Maintenance Mode is enabled (or using plugins like Coming Soon Page, Maintenance Mode,…)
– The WP REST API is disabled by a security plugin (for example WP SpamShield and its Disable anti-spam for miscellaneous forms option )
you are using a captcha or something similar that restricts the access, for example by using reCAPTCHA
– The wp-admin not directly accessible (Clef), or because the website access has been limited through the .htaccess (the Authentification Required popup)
Once you found why it is not working, you need to find an alternative to do what you need. If it is a security plugin or else, you need to check with them how to keep have the WP REST API enabled.
Your PHP error logs are made accessible by your hosting service, if you don’t know where they are, the best is to ask them. You can also try to use such a plugin as Error Log Monitor (but they don’t always detect the error file). If you are willing to learn more about checking errors by yourself, check this: Monitor PHP Errors. Be careful, the PHP Error Logs is not the Access Error Logs, they are two different things.
Your PHP error logs are empty? It might not be normal, PHP error logs usually have notices, warnings, and errors. Please make sure the errors are actually being logged. For that, you can edit your functions.php (what is functions.php?) and insert such a line:
error_log( “Hello Error Logs!” );
Then load any page on your website, and check your PHP Error Logs again. If they are empty, it means that they are not working. Contact your hosting service in that case. Don’t forget to remove this line from your functions.php.
Alternatively, you can also have a look at your WPLRSync.log located in your Documents folder, it sometimes contains interesting information.
I had myself issues with plugins such as Media Library Assistant and WP Fastest Cache.
Did nothing work?
I will not be able to give you more advice than what is on this page. The only way to debug your issue further is to:
- Get your PHP Error Logs. This file is really necessary for debugging the issue. If you don’t find it, or if it is empty, have a look at this: How to Debug WordPress.
- Get your WPLRSync.log. This file is on your own system, in the Documents folder. If it is huge, delete it, reproduce the issue, and get the new WPLRSync.log file.
- Contact me, and share with me those two files, and possibly, access to your install.
It is really important to follow this process to make sure that I can help you. Thank you.
