Concerned About Upgrading Server PHP with ZC version 1.3.8a

[starrysky]

Hi Balihr,

Unfortunately, the server we migrated the site to does not allow external certificates to be installed. So, until we migrate again, we need to just disable it. It isn't worthwhile to pay almost $200 from the hosting company for their own SSL certificates.

Where can I get them for free? That would be great, as I have a couple of other sites that I DO need SSL certificates for. Thanks!

I am having a couple of other issues, after getting the SSL false to work. When I go to a product information page, and update a product (to have a quantity of zero, for example), and click save, then click update, I am given this error message:

Fatal error: Call to undefined function usu_reset_cache_data() in##.../admin/product.php##on line##17

I am not sure where I would define this particular function, as far as what I would place into which file.

In addition, when I click on the MyAccount link on the cart itself, it goes to an error page that says:

CAPTCHA Error: GD-Library does not support JPG. The CAPTCHA cannot be used!

Where would I place a new captcha file, and are there any examples that I could use for a new file?

Thanks in advance for your help!

If your host charges $200 for SSL certificates, I'm guessing you don't have Let's Encrypt as an option in your cPanel... But then again, what are you still doing with that hosting company?
Try to Google "free ssl certificate" and you'll get plenty of results. The downside is you need to renew every 30-90 days. If your host offered Let's Encrypt, that cert would automatically renew every 90 days and you wouldn't have to worry about it ever again.
I know there are hosts that sell SSL certs at ridiculously high prices and with margins over 1500% (no, that's not a typo), but that's a whole different topic...

IMHO, if you don't want to bother and spend time renewing your cert every month, just grab your wallet and cash out the 5 bucks and sleep tight for a year. Or, 15 bucks for 4 years validity... Is that even worth thinking about? I'm not sure if it's against the rules to post the link, although I'm not affiliated or anything, but check ssls.com and their PositiveSSL.

As for the rest of your problems - sorry, but I have no idea. You're using a system that has museum value and much has changed since. I'm guessing the USU error is because you're missing the functions file. Try creating a file in your admin/includes/functions/extra_functions/usu.php and put the following in that file:

It's something I pulled from USU 2.215 but I have no idea if it'll work.

Captcha error - are you sure you have GD library installed on the server?

[starrysky]

Hi Balihr,

Thank you so much, the file you suggested i upload did the trick!

As far as the captcha, we found an older file, we just had to reactivate it.

Are you familiar with any lazy loaders that might work on this site? I see there are a few different options that work with ZC. Perhaps the "Image Handler" plugin would also add this functionality, but that seems to just reduce the image sizes. I would like a lazy loader as it could potentially reduce the load time of some of the pages that are rather image heavy. Thanks again, and thank you in advance for your suggestions

[balihr]

Image Handler is helpful because you load a resized image, so instead of loading a let's say 500 kB image, you're loading a small size version of maybe 30-50 kB. Now, on a product listing page, where you're loading 40 images, the difference is huge.

IH doesn't add lazy loader, but can be modified to include it. However, this is up to you how to implement it. There are also numerous jQuery plugins available that can do lazy-loading, but I don't recall seeing anything ready-made for Zen Cart. I might be wrong, tho.

[sw1138lr]

We are currently on version v1.5.5a using PHP 5.6. We have our DEVELOPER site pointing to PHP 7.3 and it's working. What are the consequences of moving to PHP 7.3 and staying on ZenCart version v1.5.5a?

Please only post in one thread. It confuses us old folks.
