 * Hi guys
 * I found that the Contact Form 7 forms had stopped submitting on some of our websites
   with the following error in the console:
 * TypeError: data is null
 * After investigating, I found that it was a conflict with another WordPress plugin–
   the Password Protected plugin (the one by Ben Huson). This was with the current
   versions of both plugins – v5.0.2 for CF7 and v2.2.1 for Password Protected. 
   Deactivating the Password Protected plugin allowed the forms to submit properly
   again.
 * Note – even with the PP plugin activated, but not having the password protection
   turned on still stopped the forms submitting.
 * I’m not sure which plugin will need updating to fix this, so I’ll put it on both
   support pages so everyone is aware and provide a link to the other thread.
 * Thanks
 * Here’s the link to the Password Protected support page:

 * Following an update to the Password Protected plugin this now appears to be working
   fine for me – here are the versions I’m now on:
    - Password Protected – 2.2.2
    - Contact Form 7 – 5.0.2
    - WordPress – 4.9.6
 * Thanks guys

 * Update – I found that things were working fine while testing in Firefox, but 
   we’ve just found that an error still occurs in Chrome:
