Hello,
I had this error on several single product pages:
Warning: array_push() expects parameter 1 to be array, string given in …/wp-content/themes/royal/framework/woo.php on line 1344
Warning: implode(): Invalid arguments passed in …/wp-content/themes/royal/framework/woo.php on line 1344
I fixed it by clearing cache and deleting cookies but I am afraid that this error will appear again, also for my customers.
Any idea why this happened and how it can be fixed?
Many thanks in advance!
