Downloads remaining goes to 3 from 5 after one click

[verzea]

I'm selling digital products since 2009. Never had this issue. Recently I changed the theme and updated to v1.5.4. Today someone had problems with one of the downloads and received a message about page doesn't exist. I updated the order over and over until I investigated the case. All my downloads are set up to 7 days and 5 attempts. My recent orders have 3 remaining downloads (that means the customers downloaded once). I also experimented with a fake account and after 2 clicks (downloads), the order expires!
Please help.
Really appreciated!

With theme are you using? Where did you download it from?
What other Addons are on your site?
Please supply a detailed list of ALL the ways in which your site is different from an original fresh install of v1.5.4.
Whats the URL?

Theme used: Carlisle Fresh from Picaflor Azul
Addons: Zen Lightbox and Ultimate SEO
Nothing special, I did a regular update (re-install the zen cart with DB update and then I added the theme and those 2 addons).
Url: www.arc4studio.com/store

PPP version?
mysql version?
hosting company?

i can't duplicate the problem here, so trying to figure out what's different on your site vs mine.
I asked ajeh about it and she said she can't duplicate it either.

Fact that store is in a subdirectory, possible an issue with an .htaccess file? Have seen the same decrement of downloads by one when a download fails due to possibly incorrect temp folder permissions (777 applied when host only accepts 755) or other follow-on errors occur.

Found it! Thanks. The unusual behavior was caused by the missing /pub directory from my installation. It is something that I deliberated removed after install (don't ask me why :)). Now it seems to be ok. Thanks again.
