Hi, I was wondering which kind of browser you were using? I’d love to dig into this, as I tested it against Chrome, Firefox, Safari and even Edge.

PS: sorry for the very late response. I didn’t get a notification of your first message.

Glad I could help out.

Are you using Safari to surf? If so, does the issue occur when you use another browser (Google Chrome for instance)?

To be honest, every plugin needs to be loaded while running the bootstrapping process of WordPress (which happens when a visiter tries to load the site or you work in the backend).
The more plugins, the more memory will be required. Usually, I advise everyone to keep the number of plugins limited (5 to 10 if possible) to keep memory usage as low as possible.

There’s a way to measure which plugins use most memory. Ironically, it’s a plugin that checks that: https://www.ads-software.com/plugins/p3-profiler/

I’d suggest you go about this as follows:
– Disable all plugins
– install P3
– Reactivate a couple of plugins
– Run the P3 scan
– Reactivate some more plugins
– Run the scan again
– …

Eventually it will become clear which plugins use the most cpu and memory and might be the cause of this out of memory error.

To solve it, you’ll have 2 options (neither are great though):
– Increasing the php memory_limit (needs to be done with your hosting company, might require an upgrade)
– Decreasing the memory usage (usually easiest by deactivating plugins)

Glad to hear it’s fixed ??

It seems not all W3 Total cache files were removed. Can you manually (via FTP or SSH) remove following files:

/home/santoria/public_html/wp-content/object-cache.php
/home/santoria/public_html/wp-content/advanced-cache.php

How many plugins do you have active? Is it an option to disable one or more?
By default, WordPress only uses about 32 MB of memory. However, the use of plugins does increase the memory usage substantially.

Would you happen to have W3 Total Cache active before the upgrade? I’ve encountered a couple of cases where this broke the upgrade process.

In most cases it was resolved by removing all W3 Total Cache related files via FTP, completing the upgrade and then reinstalling W3 Total Cache.

Glad to hear! Have a great weekend!

Strange, it seems the limit hasn’t increased above 192 MB

187 957 248 bytes =
187.957248 megabytes

Doesn’t really matter, since a WordPress site should rarely use that much memory. Can you indicate me how you disabled all of your plugins? Did you do this via the database or another way?

Sure, glad I can help out. Keep me up to date if one of those options doesn’t fix it. Glad to look into further if needed!

Nevermind, Lorro already replied while I was composing my initial answer.

In quite a number of cases, you can fix the “Cannot modify header information – headers already sent”-error by enabling “output_buffering” in your PHP configuration. Might be worth a shot.

I’ve also had very good results using following plugin to do the same thing: https://srd.www.ads-software.com/plugins/velvet-blues-update-urls/.

A good way to find out what is causing the delay in your sites loading time would be to do following 2 things:

– Perform the test on https://gtmetrix.com/. This will tell you where your site needs to be optimized
– Install and run following plugin (after the gtmetrix test has finished): https://www.ads-software.com/plugins/p3-profiler/. This will show you if there’s one or more plugins causing too much load and thus slowing down your site.

Feel free to pass along your url’s. I’d be happy to take a look myself.
