Just last night encountered a similar error, and had to disable WebP to restore the site:

I’m now holding off on updates at other sites where I’ve been using the plug-in, with success and satisfaction, I might add!

Same issue. Broke on update.

Same here – seems to be a problem with the code running before init.

I had the same issue. I was not able to log in to the admin panel. I disabled the plugin by editing option active_plugins in wp_options table usnig phpMyAdmin.

I’m a fan of the plugin, and have it in use at a number of sites, but I’m wondering now if I’m going to have to switch to something else. It’s not a good sign for a plugin when a fatal error on update issue isn’t at least rolled back via new updates until solved.

Same issue here.

Same problem on several sites, just after upgrading to WP 5.3 and then upgrading WebP Express from version 0.14.22 to 0.17.2.

I solved it by disable any image compression plugins like Smush or Imagify

Though I’m able to install and use fresh versions at multiple sites, in addition to the already-reported issues I also ran across an issue of not being able to install it via function, when other plugins using the same function (the widely used tgmpa.php class) install fine.

Found the bug. The migration is run too early. It must wait for the admin_init hook. A similar problem was encountered here:
https://wordpress.stackexchange.com/questions/352896/error-call-to-a-member-function-switch-to-locale-on-null-during-insert-with

In ‘lib/classes/AdminInit.php’, the line saying “self::runMigrationIfNeeded();” must be moved into the “addHooksAfterAdminInit” function.

I shall create an update.

Sorry btw. for not reacting to this promptly. Something else has been requiring all my attention and I saw it necessary to pause development and support on this plugin. This other thing still requires a lot of my attention, but I hope to be able to at least fix serious issues like this

Still a great plugin – looking forward to getting the fix. My unsolicited advice to you would be to come up with some “pro” features – to incentivize people to pay you for it and yourself to stay on top of things. Thanks!

Just published the fix in 0.17.3.

@ck-macleod: I have considered a PRO version. But right now, it is more time than money that is the low resource. As creating a PRO version takes time, it is not going to help me stay on top of things ??

Hello, we are using WP 5.3.2 and tried to update the webp plugin and it crashed the site as with the others… I then deleted the plugin dir, was able to get back in, then installed the plugin, 1.7.3 by uploading it from plugin site and get same result it crashes the site.

Any ideas what to check.
I do not have any smush plugins on the site.

Thanks..
Have a great day!
