Ultimate Member Form Slow when Cache is off, but broken when Cache is on

@mouschi

How many fields do you have in this Registration Form and are there any Conditional fields?

16 fields, none are conditional. all are text input or radio buttons, except for one calendar with date picker.

@mouschi

Let GTmetrix test your site.

i tested 2 pages: the form page, which shows load time of 10.3 seconds and another page that just has links, which loaded up in 2.1 seconds

through gtmetrix, that is, of course!

1. Which PHP version are you using?

2. How much memory is PHP allowed to use?

3. Which Page Builder are you using?

4. Do you have any custom code in your active Theme’s functions.php file?

5. Enable PHP error logging if the debug will give some more info about this issue.

Read this guide: “How to enable debug logging”

https://docs.ultimatemember.com/article/1751-enable-debug-logging

You will probably get a PHP log file with notices and some errors in this file when you do the tests: /wp-content/debug.log

Post the content of this file here in the Forum and we can give you the PHP error explanation. For best formatting use the CODE format.

Try to increase your memory to use for PHP.

https://elementor.com/help/requirements/

WP Memory Limit

WP Memory limit of 256 MB (Elementor and Elementor Pro only), 512 MB recommended, 768 MB for best performance.

Note: These requirements are for Elementor. If you are using additional plugins on your site that also have minimum requirements such as WooCommerce, you may need to increase your memory to 512 MB to help avoid loading issues. See also, the following documentation.

Hmmm … ok i’ll try that right now and report back

Ok I just updated to 512mb and confirmed that was reflected properly in phpinfo() and there is no change, so it is still not loading well.

@mouschi

Try to update to PHP Version 8.0, most plugins are supporting this version now.
Keep the PHP Debug enabled if there are any plugin with issues.

hmm that wouldn’t have any affect on the loading unfortunately. heck, i think rackspace only offered 8.0 in the past couple months or so.

@mouschi

I’m using PHP Version 8.0.28 without any issues.

If I were a betting man, I’d say that there is no way upgrading from 7.4 to 8.0 makes the site go from running terribly to decently. I’ll do the update if necessary, but I think it will not do anything at all. I’ve never seen a php update solve load issues for a simple form like this. What would be the next step to check if the 8.0 update doesn’t help?

@mouschi

Ask your web hosting support if they can help you when your WP plugin cached page loads fast and the non-cached page loads between 10 and 20 seconds.

Where are you spending the time: UM, Elementor or the Theme.
