Where are you seeing those errors? Can you please give me a bit more information? I went to your site but it seems to be ok. * Warmly, Mihaela * [itmjlee](https://wordpress.org/support/users/itmjlee/) * (@itmjlee) * [5 years, 11 months ago](https://wordpress.org/support/topic/404-undefined-error/#post-12996223) * Hi [@mplusb](https://wordpress.org/support/users/mplusb/), * It seems like I am having the same issue as [@kosmomehow](https://wordpress.org/support/users/kosmomehow/) mentioned above. * The 404 undefined error raises when the lazy load option is enabled. * I checked there is no error in the console after turned off that option. * Would you able to have a look and fix this problem? * Thanks MJ * [iigen](https://wordpress.org/support/users/iigen/) * (@iigen) * [5 years, 11 months ago](https://wordpress.org/support/topic/404-undefined-error/#post-12996678) * Hi [@mplusb](https://wordpress.org/support/users/mplusb/)! * Same issue for me. Just in case some details, I have same conditions – the 404 error appears only with lazy load option enabled. - This reply was modified 5 years, 11 months ago by [iigen](https://wordpress.org/support/users/iigen/). * Thread Starter [kosmomehow](https://wordpress.org/support/users/kosmomehow/) * (@kosmomehow) * [5 years, 11 months ago](https://wordpress.org/support/topic/404-undefined-error/#post-12997790) * I can confirm this is happening when lazy loading is on. It’s one of crucial functions to optimise page speed, any idea when you will be checking and possibly fixing this issue? * [Miha](https://wordpress.org/support/users/mplusb/) * (@mplusb) * [5 years, 11 months ago](https://wordpress.org/support/topic/404-undefined-error/#post-12997869) * Hi guys, * Thank you for letting us know about this! Is it possible to send me the url of a page where this happens so we can investigate? Also, are you using just Modula lite/free or do you have the Pro and other addons installed? * Thanks, Mihaela * Thread Starter [kosmomehow](https://wordpress.org/support/users/kosmomehow/) * (@kosmomehow) * [5 years, 11 months ago](https://wordpress.org/support/topic/404-undefined-error/#post-12998026) * Hi Mihaela, * [https://makuli.pl/florystyka-i-dekoracje/](https://makuli.pl/florystyka-i-dekoracje/) * I’m using free version. * Thanks * [Miha](https://wordpress.org/support/users/mplusb/) * (@mplusb) * [5 years, 11 months ago](https://wordpress.org/support/topic/404-undefined-error/#post-12998437) * Thank you [@kosmomehow](https://wordpress.org/support/users/kosmomehow/)!
