I just upgraded my browsers, FireFox and Safari to the latest versions this week and now Zen Lightbox no longer displays the larger images.
That's because you're using outdated software (both ZC and ZLB) with modern, updated browsers.
domnz:
I am running Zen Cart 1.3.8a. What is the latest version of Zen Lightbox I can install that will work with Zen Cart 1.3.8a?
For ZC 138, you can only use the version of ZLB designed to work with that version of ZC.
domnz:
Is anyone else having such issues ?
Anyone running ZC138 and an equally old version of ZLB would be having the same issues.
domnz:
Why would Zen Lightbox stop working with the current web browsers?
Zen Lightbox is updated as browsers are updated. This is because Zen Lightbox and browsers work together to serve your page's content (as would be expected). Additionally, Zen Lightbox is updated as Zen Cart is updated so they will be compatible together.
domnz:
Can I change something in Zen Lightbox for it to work with the latest browsers?
ZLB is already updated to work with the latest browser. But it won't work in your very old, very unsecure store.
domnz:
I don't want to upgrade Zen Cart because that's a massive task as my Zencart is very customised.
I completely understand what you're saying here - it can be a daunting task to upgrade when you have a heavily customized store, but this is a poor excuse for putting your customer's data and financial safety at risk. If you're going to be in business, then you have a responsibility to those people who keep you in business - your customers. You owe it to them to have a safe, secure store which protects their data, their finances, and their identities.
Best advice - put your nose to the grindstone and do the upgrade. It's not as hard as you think it is. The instructions appear overwhelming because there are so many steps when you're heavily customized....but all those steps are PRECISELY what makes it easier to upgrade than it would appear because they walk you through the process.
If you don't want to do this, then your alternative is to say goodbye to the lightbox (and to other addons as well) as they will likely begin to fail one by one as technology leaves your store/business in the dust.
Your choice.
Good luck and happy Zenning :)
