Drupal 7.x

Hi guys,  very stupid question though, I have reinstalled WP on top of my drupal site. I thought I don't have anything to do a backup, now I realized that there are actually some pages I wrote in my old site. Is those text available in some source code that I can extract?

i need to use a field value from the last post user submitted and ad to it value from the new post.

Here is the scenario:

1.User A submitted post with field_a value 10.

2. The next day user A submit field_a value 5. Field_b becomes 15. It took the values from today and and the yesterday’ Post and added them up.

3. It should only add up values from the same user.

I would appreciate the direction or solution. Thanks.

Hi folks

Looking to set up a bunch of QR codes to open some training videos. Trying to future proof them somewhat so that if the video has to be edited the QR code will still be OK (they will be affixed to various parts of a vehicle so hoping to not have to send out replacement QR codes). Looked into dynamic QR codes but has the potential to be costly and an ongoing cost as I couldn't track down any open source scripts for dynamic URLs just paid (with monthly subscriptions - cancel account, QR dies).

Emails (all system / rule based emails) work fine unless a user checks ' Plaintext email only' option in their user profile. When they have it checked, the email fails with a message to contact the system administrator.

I have the following mail/smtp related modules installed:
-Mail System
-Mime Mail
  -Mine mail action (disabled)
  -Mime mail CSS Compressor (disabled)
-SMTP Authentication Support

Looking at the logs, you first get an error with the message:

The other day I was performance testing the bunny module, but when I tried to get to 100 requests/second the kernel crashed so I had to back off to only 60/second, but the system when put in production should handle 1000/second, but this bug will be a problem. Has anyone seen this with a drupal module?
