using zen 1.5.5 and PHP 5.6. When i try to upgrade to PHP 7.0 or PHP 7.2, all my categories do not show up on the website. The category pages do not show any sub-categories. i've attached the same page using PHP 5.6 and PHP 7.2

actually when i try to upgrade to PHP 7.0, i get mysql errors and no pages come up. PHP 7.2 brings pages up but shows no subcategories.

7.2 will not work...

i had some problems with 7.0.

did you try it with 7.1?

rather than providing screenshots, do you have any log files? but i would first try 7.1.

7.2 does not play well with any released ZC version. see:

try 7.1 and post any log files if it does not work.

best.

for some reason my server configuration doesn't have 7.1 installed.

contact your host and find out why.... i would be curious....

7.1 is still in support:

manually upgrading all of you zc 155 files to make it 7.2 compatible is a lot of work, and would be redundant once the next version of zc comes out and you decide to upgrade.

This thread is not clear.

The current Zen Cart 1.55f will work up to php 7.1, so anyone being forced off php5 by their hosting should upgrade to this version.

Hosting should offer php7.1, no reason why they cannot.

If you must use 7.2 you will have to manually integrate the changes made in the 1.56 development branch on Github to be compatible with 7.2. Not recommended at all.
In my opinion it would be quicker/easier to change to a host that does allow 7.1.

Ya, the general consensus is that PHP 7.0 is pointless since 7.1 is even faster and mostly no breaking changes between 7.0 and 7.1 -- It's rare to see 7.0 on a server nowadays.
Usually I see 5.6, 7.1, and 7.2.

Next month when 7.3 is officially released I expect it to replace 7.2 while I think we'll still see 5.6 and 7.1 offered for awhile yet (despite them being officially unsupported by end of year). That said, I'll always recommend the newest version that's compatible with your app (ie: ZC and your plugins) requirements.

Note that all PHP versions below 7.2 will go out of support by the end of the year.

got my hosting company to add PHP 7.1 and i moved the website to 7.1 but the same thing happens that happened in PHP 7.2 - Subcategories do not shop up on any pages (see my screenshots above). Also, using PHP 7.1, my admin area brings up a BLANK screen.

The log file is empty after upgrading to PHP 7.1 and still admin section is blank and no subcategories are showing up on the site.
