Unsupported operand types: string * int

[lostmail]

HI there,
I set in my htaccess from AddHandler php74-cgi .php to AddHandler php81-cgi .php

Now I have the problem, that i get this message when i click categories/sub categories:

"0 Unsupported operand types: string + int"

I have an older backup as test environment which i updated with to current joomla and vm but here the error message is not coming up...same server/webspace.

Any idea what is crashing the category navigation ?

Another strange thing is that in category navigation some links open the subcategories and some links don`t open them (but they have su-categories) - than only the category overvie in main page is visible but not in the category navigation tree.
But clicking a sub category in main page the same error message comes up
"0 Unsupported operand types: string + int"

Changin back to PHP7.4 the problem does not exist (beside the trouble with the not showing sub-menus in category try at some main categories..some slide out the sub categories - some not)....

Thank you.

Currently VM supports up to PHP 8.0

Changed to 8.0 - same problem

you need to provide an error trace ... no one can just "guess" where this error comes from..

Could just as easily be from a 3rd party ext or template

Switched shop/configuration/templates to category template vmbeez3 - Standard and now I receive some more information:

In line 9 I found:
$ndate = strtotime ('now') - ($days * 86400); ?>

Is that a problem in php 8.0 ?

Commented out this line for testing in /templates/horme_3_pro/html/com_virtuemart/sublayouts/badges.php:9 :

//$ndate = strtotime ('now') - ($days * 86400); ?>

Now the site works....categories and products are now loading.

What does PHP8 have a problem with this line ?

Same as in this thread:  http://forum.virtuemart.net/index.php?topic=149069.msg533461#msg533461
