    I'm using the Dendrite theme on my website. Ever since updating my PHP from 7.2 to 7.4, I get the following error on my admin screen:

    Warning: Creating default object from empty value in /homepages/12/d255306550/htdocs/lonegenius/wp-content/themes/dendrite/includes/redux-framework/reduxcore/inc/class.redux_filesystem.php on line 29

    And the following one on my homepage: 

    Warning: Creating default object from empty value in /homepages/12/d255306550/htdocs/lonegenius/wp-content/themes/dendrite/includes/redux-framework/reduxcore/inc/class.redux_filesystem.php

    I'm running the newest Wordpress. An older, slightly modified version of Dendrite. Please let me know what other information you need to help diagnose this. It seems specifically limited to the Redux Framework (not familiar with that).

    Hi Neuron team,

    I have the same issue but the plug-in seems only fix the issue on desktop, I'm still seeing the same warning when I navigate my site mobile (both Android/iOS).

    Thanks,

    Coty
