Too simplistic, Does Not handle serialized strings

Many plugins use “serialized data”, several settings put into one field in the database. The length of each setting string is stored along with the setting.

If you use a tool that replaces text without replacing the length of the text in the serialized data, your data is messed up for the plugin.

The Changelog says “Exclude serialized data from replace function”.

Find another tool. I’m trying “WPEX Replace DB Urls” next, which specifically says “Serialized strings are also supported. You can replace a URL with another.”
