Not working with WP Multisite

can confirm.

common.php (line 3728 and 3066) causes the error in Multisite when allocating memory.

Indeed ??

Please try disabling the EWWW debugging setting and then re-upgrading and let me know what happens.

When/if it breaks, you can just delete the plugin folder, and reinstall 2.5.4 from here: https://downloads.www.ads-software.com/plugin/ewww-image-optimizer.2.5.4.zip

Potential fix, soon as I have confirmation from someone (besides myself) that it works, I’ll release it officially: https://downloads.www.ads-software.com/plugin/ewww-image-optimizer.zip

Hi,

Thank you, replacing with your new folder just now brought my site back from 500 Internal Server Error limbo.

Merry Christmas,

Just rolled out 2.5.6 with the fix!
