Big Grid Slide disappeared after upgrade to 7.5

Hello,

I’ve just upgraded from 7.4 to 7.5. Several aspects of the site are not working properly mainly on our homepage.

First, we use a News ticker and a Big Grid Slide at the top of our homepage. Following the upgrade, without changing anything, the slider has stopped rendering on the homepage.

Here is our Visual Composer Layout:

Here is what is rendering on the homepage:

I checked the source code of the page and the element is simply not there.

I thought I’d check and see if TagDiv Composer might be of use. When I attempted to use it, I got the following error:
Fatal error: Access to undeclared static property: td_global::$td_options in /homepages/40/d181305078/htdocs/kwinix/nextgenindy/wordpress/wp-content/plugins/td-composer/includes/tdc_main.php on line 388

Finally, we use Block 1 at the bottom of a two-column row. In Newspaper 7.4, the block formatted itself into two columns with the big story on the left and four smaller ones on the right. Now, it spans both columns.

Any help with these issues is appreciated with the Big Grid Slide being the most urgent.

Thank you,
Ben

I have resolved two of the three issues above by deactivating the tagDiv Composer plugin.
