I had a wordpress install with the previous version of wordpress and the previous version of acf with the additions of some of the add-ons. The whole site was basically a flex-content based site, and all the fields were working properly up till the updates. Data in the fields are still saved, but when updating any of the fields or adding new fields and inputting data, it no longer saves that data.
As for debugging, i attempted to turn off all plugins, and reactivate only acf related plugins and the problem still persists. Ive also switched themes to wp 2012/13 etc, to no avail.
