In the case of Contact Form 7’s corrupted serialized data, it was a problem with a URL, but there is no URL in this field.
I had checked all the value lengths in the problem ACF field object and they’re all ok:
a:10:{s:5:”label”;s:28:”Interior Dimensions Imperial”;s:4:”name”;s:28:”interior_dimensions_imperial”;s:4:”type”;s:4:”text”;s:12:”instructions”;s:77:”Enter the interior imperial dimenions, using this format: 12”L x 34”W x 56”D”;s:8:”required”;s:1:”0″;s:13:”default_value”;s:0:””;s:10:”formatting”;s:4:”html”;s:17:”conditional_logic”;a:3:{s:6:”status”;s:1:”0″;s:5:”rules”;a:1:{i:0;a:3:{s:5:”field”;s:4:”null”;s:8:”operator”;s:2:”==”;s:5:”value”;s:0:””;}}s:8:”allorany”;s:3:”all”;}s:8:”order_no”;i:5;s:3:”key”;s:7:”field_5″;}
The only other thing I can think of is that this Instructions field contains quotation marks (denoting inches), and all of the database entries for that field contain quotations marks. There’s another field for metric and it shows up fine, but has no quotation marks. Could it be some sort of character encoding issue when I moved the database to a new server?
Or a serialized data issue with quote marks?
