When something new comes up like this, it’s good to look at what has changed…like a theme update, new plugin, etc.
I don’t quite have enough information to answer specifically…frontend or backend? Are you using the search add-on? Where do you see the error and what exactly was printed to the screen?
Usually, when a 500 is encountered, WordPress sends an email to the administrator. That email will have the specific error, which is a necssary piece of information to know what happened. Catching the error in the error log will probably require that you have a php error log set up on your server, the plugin’s debugging log probably won’t catch it.
The missing template message is not related to the 500, to check on that, look at the [pdb_login] shortcode and make sure the “template” attribute of the shortcode is correct.
The HTTP 500 Error (that reads below) occurs on all pages, starting with List Participants. The commonality seems to be in admin.php.
“This page isn’t working right now
http://www.sitenamewithheld.com can’t currently handle this request
HTTP ERROR 500″
The error occurs whenever the following happens. The page is listed, followed by a hyphen and the button clicked.
List Participants – Filter
Add Participant – Submit or Apply
Manage Database Fields – Update Fields
Manage List Columns – Have not tried to see if it works
Import CSV File – Have not tried to see if it works
Settings – Save Plugin Settings
Combo Multi Search – Save Changes
Field Group Tabs – Save Changes
Participant Login – Save Changes
The URL’s for the HTTP ERROR 500 are as follows:
http://www.rfpi.com/wp-admin/admin.php?page=participants-database
http://sitenamewithheld.com/wp-admin/admin.php?page=participants-database-add_participant
etc….
The error seems to be in admin.php
I will look into the PHP Error Log
When looking at the error logs I see the following:
[Wed Mar 29 08:37:18.866859 2023] [proxy_fcgi:error] [pid 2661:tid 140307916121664] [client 65.109.208.239:60646] AH01071: Got error ‘PHP message: PDb_shortcodes\template::find_template custom template not found: “/home/namewithheld/public_html/wp-content/participants-database-templates/pdb-login-default.php,” using the default template; PHP message: PDb_shortcodes\template::find_template template not found: /home/namewithheld/public_html/wp-content/plugins/participants-database/templates/pdb-login-default.php; PHP message: PDb_Login::template_path couldn’t find template at using default. ‘, referer: http://www.sitenamewithheld.com/member-login/
When I look in the folder given in the error log I don’t see “pdb-login-default.php” in ……../home/namewithheld/public_html/wp-content/participants-database-templates/pdb-login-default.php
I have tried reinstalling the plug-in per the instructions from this website, but that didn’t work either.
You’re looking for a “fatal error” that is the reason for the 500. The login template messages are only informational debugging messages, not errors.
To solve this, we must see the specific error that is causing the problem.
The error that I posted came from the Apache Access Log and not from the Participant Database Debugging Log.
I tried using a different computer and a different browser (Brave). I doubted it would make a difference, but at least this time I got an error message of “Sorry, that page is missing”. This is very frustrating. I have never had a problem with this excellent and very useful plugin.
What you’re looking for is a “fatal error” without that I really can’t help you, I’m sorry, but without that, I have no idea what the problem is.
Did you check for an email from your WordPress site to the administrator? That is usually the easiest place to find the specific error.
I don’t get any emails from WordPress. Where else would I be able to find these “fatal” errors?
I just noticed that I am having the same issue with my other plugins. This is not a plug in issue, it’s a WordPress issue. Thanks for being very responsive today.
