So, its not just me! I had PayPal on the phone with me for 2 hrs.stright, and could not beat this issue. So, I carried on a few days more on my own, and I did "many different" things and finally it appeared [my paypal logo] but not without yet another problem. But what I did was to disable, not uninstall, [all] payment modules], and [payment logos modules] then I reset my paypal module and reconfigured it, then I used my prestashop cleaner [only] to [clean/optimize data base] of which it did so, and [repair or fix broken data] of which it did so, and then my module paypal button appeared. At one point paypal thought it was my mis-configuring something, as did i. [ I spent a lot of time on this [6 days]. Any way, now I can get to paypal in a practice check-out, but now it tells me that there is something wrong with my e-mail and It wont let me go any further, so, here I go again! While I was configuring my paypal account, in paypal mngr, I got as far as the [integration] and clicked [save & publish] it seemed nothing happened, so I re-configured it again and again, Then I got wondering if the [button] just might be really there but invisible to me be cause of some mis-configuring on my part. Right now I am not sure what finally did it cause I did so many things and I cant remember all of them, but I was thinking its my fault. It bewilders me to find that paypal, or their modules aren't preconfigured to just sign-up, press go and its done. I also "un-installed" the [Advanced EU Compliance module] prior to using my prestashop cleaner module. And a little something I`d like to pass along. I just got a phone call from a middle easterner or?? and he said he was calling from Microsoft Cntr. and wanted me to go to a website so he could remove all my viruses etc. Warn your friends and give them NOTHING. I wish I could have understood him better and got the website from him, He wanted to guide me to the site over the phone but I told him I didn't trust him at all and i hung-up. Remember, if you own a business, you need to protect it even more so due to your Financial accounts etc. I hope this helps in even the smallest way. Kenny j
