WP_MEMORY_LIMIT or WP_MAX_MEMORY_LIMIT ?

the more you know

By default, WordPress enforces a memory limit of 40 MB. This means a single PHP script is allowed to use up to 40 MB of RAM. In certain cases, you may need to increase WordPress’ memory limit to run heavier plugins like WooCommerce or bbPress. To increase WordPress’ memory limit, you can define WP_MEMORY_LIMIT in your wp-config.php file using the line below.

define( 'WP_MEMORY_LIMIT', '256M' );

The setting above will allow WordPress to use up to 256 MB of RAM for each script, as long as the memory_limit setting in your php.ini file is 256 MB or greater. As is often the case with computing resources, setting a higher memory limit doesn’t necessarily increase the performance of your WordPress site. Since WP_MEMORY_LIMIT controls memory allocation PER SCRIPT, it’s actually in your best interest to set it as low as possible to reduce the chance of a rogue script saturating the RAM in your server.

Sometimes, it’s a good idea to tailor WordPress’ memory allocation separately for the frontend and backend. That’s where WP_MAX_MEMORY_LIMIT comes in. WP_MAX_MEMORY_LIMIT allows you to set a different memory limit for WordPress’ administration dashboard. This is useful because certain administration tasks require more RAM. Below is an example of how you can use WP_MEMORY_LIMIT and WP_MAX_MEMORY_LIMIT together.

define( 'WP_MEMORY_LIMIT', '64M' );
define( 'WP_MAX_MEMORY_LIMIT', '256M');

The setting above will allocate up to 64 MB of RAM per PHP script for processes spawned from WordPress’ frontend, while administration-related scripts from the backend dashboard will be able to use up to 256 MB of RAM.

Cannot find wrapper assembly for type library “ADODB”

Happy new year and Happy coding!
Using Visual Studio 2022 on Windows 11 with the latest updates to 24H2, started giving the following errors when trying to compile an older project:

The "ResolveComReference" task returned false but did not log an error.
Cannot find wrapper assembly for type library "ADODB". Verify that (1) the COM component is registered correctly and (2) your target platform is the same as the bitness of the COM component. For example, if the COM component is 32-bit, your target platform must not be 64-bit.

So, you Google a bit and find this, but don’t do that!
In my case, the following article helped, or just a comment from it “Mine was resolved by removing the reference to “Microsoft HTML Object Library” and adding it again in the project.“.

  • In solution Explorer, open ‘My Project’
  • Go to the tab ‘References’
  • Find your mentioned library on the top, in my case, ‘Microsoft ActiveX Data Objects 2.8 Library’ with some ‘ADODB.dll’ in a system32 folder.
  • Click the ‘Add’ button, tab COM > Type Libraries, and find your library, it should be checked.
  • UNCHECK it, and OK the popup
  • Repeat: Click the ‘Add’ button, tab COM > Type Libraries, and find your library, now unchecked.
  • CHECK it, and OK the popup
  • Save everything and try to compile again.

That should work.
If not, so sorry, but it did for me…

Have a nice day!


OceanWP v4.0 loses Google Fonts

Check this! All my OceanWP websites lost their default font and fell back to something Roman, so everything looked ugly! Basically all websites using OceanWP did no longer load their Google fonts after the update to version 4.0.

Solution: I had to manually enable the fonts again! How?
Go to WP Dashboard > Appearance > Customizer > Typography > Google Font Settings and enable Google Fonts – hit “publish” and done!

Looks like someone at OceanWP forgot to check backwards compatibility…

Have a nice day!

OceanWP and SVG images

Ever tried to enable the upload of SVG images in WordPress, and kept getting the error:
“Sorry, you are not allowed to upload this file type.” ?

So, you tried the plugins Safe-SVG, disabled Wordfence, disabled Solid Security, added a snippet with WPCode, changed your wp-config.php file, and maybe some other options you found on the Interweb?
Well, if you are using the OceanWP theme like I do, then nothing will work, except when you go to your OceanWP panel, select the ‘Integration’ tab on the left, slap your forehead with a flat stretched-out hand, and finally slide the switch on that page, all just to enable the SVG files support.

Next, of course, remove all those plugins, code snippets and other things you have added to your WordPress installation and continue with your life.

Have a nice day!
