After the last update I noticed this problem popping up while trying to edit a select/dropdown from my WordPress admin.
In the WordPress admin, while editing a form, clicking on the "Edit" link for a select field which contains numeric option values was throwing this error:
Object 43 has no method "replace"
As a result, the edit options do not appear and the element cannot be edited.
Clicking on "edit" for the dropdown should have opened the dropdown's customization options. Clicking "edit" should not have generated any JS errors.
The dropdown contained a list of options with numeric values and separate text. The first option contained a value with the integer "43", and the JS was assuming ( by virtue of calling
value.replace() ) that the "value" variable would be a string. This causes an error because the .replace() method only exists for strings, not for integers.
The problem file is
js.php in the
GetFieldChoices() function. I was able to solve the error for now by adding
value = value.toString(); at around line 869, after the value variable is defined.
