I like to add that this  error above happened when I enter configuration after update and save configuration.
Before that everything work.

Ha finally. It looks like you found the reason for the not working pagination. At least it shows for me correct links now. Btw, which php do you use?

Okey, fixed next version, the code at JROOT/administrator/components/com_virtuemart/models/product.php:1055 is just
Code Select

$suglimit = intval($suglimit);
$rest = $suglimit%intval($category->products_per_row);
$limit = $suglimit - $rest;

One question when I apply your fix in product.php:1055
Should I also overwrite product.php:1054 line
I feel I should, since you define $rest In line 1056 in any case error I get is the same.
Title: Re: Error 0 Unsupported operand types: string % string
Post by: Milbo on October 05, 2022, 23:34:55 PM
The fix in the router, add at line 470 just
Code Select

$limitstart = intval($limitstart);
$limit = intval($limit);


the other code should look like that

Code Select

if(empty($category->products_per_row)){
$category->products_per_row = 1;
}
$suglimit = intval($suglimit);
$rest = $suglimit%intval($category->products_per_row);
$limit = $suglimit - $rest;

if(!empty($category->limit_list_step)){
$prod_per_page = explode(",",$category->limit_list_step);
} else {

Milbo before applying these fix I find in J4 my test site

in Gloobal configuration I have Set the pagination sequence for the List Box
Most of them empty.

Only  Backend default items per list view i have:  150

and all other no number, and when I save configuration page was broken. But I empty these few days ago when I play around pagination so I didn't connect with last update, this is reason why don't work..

Now with your fix when I enter random numbers in Set the pagination sequence in Global configuration

Everything working including pagination

Hooray :)

Thank you

Thank you again.

Yes, it is even better to leave them empty, than it creates the numbers, but if you are unhappy with them, you can enter your own. But ... most people forget that the number of article in a row determine the number to get full rows. For example you want 3 products in a row, but list 100 products, 100 is not divideable by 3. And so the automatic fits most time. the new version should have the fix already.
