    With lazysizes enabled, I’m getting the following PHP error being displayed. This is replicatable from WordPress 4.9.x running PHP 7.2 and also on the current WordPress 5.4.2 running php 7.4.7

    I have redacted the web dir path but the error is as follows. Let me know if you need any more detail.

    When lazysizes is disabled, then this error message does not appear.

    I am using the latest version lazysizes 1.2.1 however I also got it with version 1.1.0

     Warning: preg_replace(): Unknown modifier '/' in [redacted web dir]/wp-content/plugins/lazysizes/inc/Lazysizes/class-pregreplace.php on line 329

    Hello @nullport,

    The error occurs because the class attribute of the element being lazyloaded contains a slash, which the plugin previously didn’t expect. This is already fixed as part of another recent change, but isn’t in a published version of the plugin yet.

    I’m currently working on the next version of the plugin, which should release pretty soon. In the mean time, if removing the slash from the class attribute is an option and something you know how to do, that would also work. As far as I am aware, it isn’t considered valid HTML anyways, even though it works in other instances. Otherwise, the next version should fix the problem when released.

    Best regards,
    Patrick Sletvold
