Lost Custom CSS after updating Sparkling theme

This thread might give you more idea about what is going on.

Some things you can do:

  • Revert back to older version of this theme as all settings are stored inside database. From there you can copy Custom CSS that you had and take some notes for what Theme Options you had.
  • All old settings are still stored inside wp_options table options_name is sparkling-child or whatever you used to setup child theme. All settings are still in that table, so you can take a note and input them again via Theme Options.

We had to update Options Framework to address potential security vulnerabilities. This is a one time thing and from here you won’t experience any problems with future updates.

Sorry for inconvenience.
