Category functions (rekurseCategories) stopped working after 3.8.4.10335

[sandomatyas]

There is a site which was updated to 3.8.4.10335 (joomla 3.9.19, PHP 7.3).
The site >14.000 categories (!!!)
After that it stopped working it was generated a huge amount of sql queries like this:

Code Select Expand

SELECT c.category_parent_id, c.`ordering`, c.virtuemart_category_id, c.category_parent_id, c.virtuemart_vendor_id, c.category_template, c.category_layout, c.category_product_layout, c.products_per_row, c.limit_list_step, c.limit_list_initial, c.hits, c.cat_params, c.metarobot, c.metaauthor, c.shared, c.`published`, c.has_children, c.has_medias, l.category_name, l.category_description, l.metadesc, l.metakey, l.customtitle, l.slug
FROM wde0w_virtuemart_categories as c
LEFT JOIN `wde0w_virtuemart_categories_en_gb` as l ON l.`virtuemart_category_id` = c.`virtuemart_category_id`
WHERE (c.`category_parent_id` = 6456 ) AND c.`published` = 1
ORDER BY c.ordering, category_name ASC
I digged a bit and found mod_virtuemart_category which I disabled and the site is working. I checked the code and this is VirtueMartModelCategory::rekurseCategories
Also backend category dropdowns are generated very slowly

Have you ever faced with this issue?

[pinochico]

yes, then we developped our modul and our function.

I have an other category module too, but would be better if the core functions could do the job

[pinochico]

If we bought any extensions from Joomla (or VM)

everytime we change/develop different version from original, because is not correct for:

- using with another extensions together
- using for real bussiness

Sometimes we developped a lot of hours or months.

Yes, would be better if the core function could do the job, but i not possible, when extensions is not from one developer only. (a good developer).

But you can buy subscription and send info to Max.
