Comment (by jdw0203):

 Hi,
 I'm managing at least 4 sites which are all affected by this issue. Each
 of the 4 sites are wordpress, running Divi theme with Woocommerce and a
 number of other plugins installed. All are almost identical in terms of
 the plugins used on each. All are sitting on shared hosting servers.

 The first 6 lines of the error log are:

 {{{

 to be array, integer given in /home/mysite/public_html/wp-includes/class-

 }}}

 The last 3 lines shown above infinitely repeat themselves until the error
 log grows to a large file size, which then maxes out the disk space
 available on each hosting service.

 I've been experiencing this with all 4 sites since early December, when
 the last major Wordpress update rollout occurred.

 Is anyone willing and able to help debug this issue?

 Desperately seeking assistance with this pain in the behind issue.

 Cheers
