* System Status

[10] Fix | Delete

* Here we note system settings that could potentially cause problems. An extended view (displaying all settings we

[11] Fix | Delete

[12] Fix | Delete

* Elegant Themes Support

[15] Fix | Delete

* If Remote Access is enabled in this section, Elegant Themes Support will be granted limited access to the user's site

[16] Fix | Delete

* (@see ET_Core_SupportCenter::support_user_maybe_create_user()). When this is activated, a second toggle appears

[17] Fix | Delete

* for the user that will allow them to enable "Full Admin Privileges" which has no restrictions (only certain ET

[18] Fix | Delete

* Support staff will be able to request that the user enables this). Full Admin Privileges can be disabled at any

[19] Fix | Delete

* time, but are automatically disabled whenever the Remote Access is disabled (manually or by timeout). Time

[20] Fix | Delete

* remaining until Remote Access is automatically deactivated is indicated alongside the toggle. A link for

[21] Fix | Delete

* initiating a chat https://www.elegantthemes.com/members-area/help/ is also available in this section.

* Divi Documentation & Help

[24] Fix | Delete

* This section contains common help videos, articles, and a link to full documentation. This is not meant to be a

[25] Fix | Delete

* full service documentation center; it's mainly a launch off point.

* Divi Safe Mode

[28] Fix | Delete

* A quick and easy way for users and support to quickly disable plugins and scripts to see if Divi is the cause of

[29] Fix | Delete

* an issue. This call to action disables active plugins, custom css, child themes, scripts in the Integrations tab,

[30] Fix | Delete

* static css, and combination/minification of CSS and JS. When enabling this, the user will be presented with a

[31] Fix | Delete

* list of plugins that will be affected (disabled). Sitewide (not including the Visual Builder), there will be a

[32] Fix | Delete

* floating indicator in the upper right or left corner of the website that will indicate that Safe Mode is enabled

[33] Fix | Delete

* and will contain a link that takes you to the Support Page to disabled it.

[34] Fix | Delete

[35] Fix | Delete

* Logs

[36] Fix | Delete

* If WP_DEBUG_LOG is enabled, WordPress related errors will be archived in a log file. We load the most recent entries

[37] Fix | Delete

* of this log file for convienient viewing here, with a link to download the full log, as well as an option to copy

[38] Fix | Delete

* the log to the clipboard so it can be pasted in a support ticket.
