I am using Custom Product Tabs for WooCommerce by Yikes.

I have upgraded all plugins, themes, etc. I deactivated all plugins. the only plug in that seems to cause it is Custom Product Tabs for WooCommerce by Yikes. If I activate that, I get the error:
Fatal error: Could not extract sufficient width/height of the gallery container. Traced measures: width:0px, height: 100px.

I have added the following CSS code but does not seem to help.

/** Fix stage height issue NextGen gallery*/
/** This may be required in multiple locations such as specific theme custom CSS options as well */
.galleria-stage { height:calc(100% – 95px) !important; }

/** Alternative solution to fix stage height issue */
/* bootstrap hack: fix content (width) inside hidden tabs */
.tab-content > .tab-pane,
.pill-content > .pill-pane {
display: block; /* undo display:none */
height: 0; /* height:0 is also invisible */
overflow: hidden; /* no-overflow */
}
.tab-content > .active,
.pill-content > .active {
height: auto; /* let the content decide it */
}
/* bootstrap hack end */

Still does not work.

Can someone please help? People at Yikes???
Thank you

Here is an example of a page with the error under the gallery tab.
