Template Issue

[sports guy]

I recently upgraded my ZC version and plugins to the latest version. But I did not upgrade my theme yet, that is a long process that I just stated last night. I assume my issue has to do with not upgrading properly by doing a complete rebuild. I have to EAT CROW with this post :)

I want to temporarily fix this current issue to buy me the time to properly rebuild the site which is going to take a bit of time. Everything shows fine except for one little area, which is the main category pages. Here is the website: http://www.throughtheagesfabric.com/ The problem only shows as a page hanging when I load any main category page. Every other page and function seems to be working except this. Even did a few test checkouts and everything else is fine. [HTML[/HTML]

So... only the primary category pages hang like this one: http://www.throughtheagesfabric.com/fabric-c-21/ All other subcategories show fine. What I want to do is attempt to fix this issue so my primary category pages show.

The error logs show this:

Would this be a specific file that shows the main category page header area? Just wondering where to look to attempt to identify this problem, but I am not sure which file might be the problem causing this hang.

You've chopped off the actual error message from the error log (besides removing the most-helpful carriage-returns). Would you post the error log details again?

sportsguy,
this strikes me as an error started when you moved from a php5.x to php7.x. php7 handles strings/integers differently than php5.x.

in the function buildBranch, i had to make the following changes:

//from
    $result = sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="'. ($level+1) . '"' : '' );

//to
    $level = (int)$level + 1;
    $result = sprintf($this->parent_group_start_string, ($submenu==true) ? ' class="'. (string)($level) . '"' : '' ); 

it looks like this could be your problem. although you class is probably slightly different from mine.

i would start there. let us know how that goes!

best.

Yeah!! This temporarily fixed the problem. I did upgrade from PHP version 5.4 to 7.1 recently. For the time being, I lowered my PHP version from 7.1 to 7.0 and now the menu works properly. Let me start by saying, I do not know PHP very well, just enough to copy and paste. So in looking at the PHP coding in this file: /MY ROOT/includes/classes/pzen_categories_ul_generator.php I did find the coding you mentioned (around line #58 and #59) an modified it, but it did not help. I assume there are other locations than just the line I found and modified (line #58 in this file).

I can live with PHP v7.0 and next time I rebuild, I think this issue is addressed in the new version of the template file. I would have never found this without your help. Much appreciated!

[carlwhat]

post the complete contents of the file and i can help point out/modify it for you...

best.

okay, i would just add 1 line and see if it works. the new line is in red. ensure that you put it exactly where i have it listed:

    function buildBranch($parent_id, $level, $submenu = true, $parent_link = '')
    {
        //resoponsive: dropdown-menu megamenu image-links-layout
       $level = (int)$level;

in addition, i believe you should change the following line (~41) as well. although please do the changes separate and test each one.

//from:
function zen_categories_ul_generator($load_from_database = true)

//to:
function __construct($load_from_database = true) 

let us know how it goes!

best.

I attempted both of your suggestions one at a a time and then both together while switching to PHP to v7.1 and in each case the the primary page hung again. I noticed a post in the theme forum where a user had error notices to mine and I believe they fixed this issue in the newer template. This might be a multiple page issue.

leave them both in... after doing that, do you have any debug logs?

the second fix is a new construct for php7.X and is really unrelated to the problem. the first fix where we cast $level to integer is the one that should address the problem. but lets look at some log files if you have them!

and it is no doubt a template issue, as this class came with the template and is not part of the ZC base.

best.
