main.js 215:23 Uncaught TypeError $this.context is undefined

It is clearly something to do with Konstra so I have added superadmin info below. There is a back end item broken as well as the blog has gone haywire.

I have also reconstructed the J3 site (with working blog) on a sandbox domain and have included the admin to that as well.

Hello?

In the silence, I have tried configuring the original item and several test menu items to 'category blog' and every single one so configured returns a 500 error.

At the moment, the sun is coming up on a broken blog so I will have to change that particular menu item and update this post with a new one for you to work with.

Your changelog shows this template to be seriously out of date.

Version 2.0.0 18 Sep 2021 Improvement

Latest version of Joomla 4 (v4.0.3) now 4.1.5

Latest version of Joomla 3 (v3.10.2) now 3.10.11

Latest version of Helix Ultimate v2.0.5 now 2.0.11

Latest version of SP Page Builder v3.7.15 now 4.0.x (v4 blank page after creating new)

We are bailing on the update - production site is being reverted as we have not heard a word from your support team yet. Credentials in the hidden area have been changed to a sandbox site with the broken J4 version which we hope to get squared away and working. You were given credentials both to J4 superadmin and to Plesk.

Page classes do not appear on the page, at least not on some pages. (Menu item > Page Display tab)

I have updated the screenshot above - now a growing gallery of Konstra errors in Joomla 4.

The missing page class is on a core Joomla page.

---EDIT---

GROK (not a true fix): I have to specifically select 'Konstra' as the template; even though it is the default, the 'default' setting does not work as expected.

How's this coming along? Three days have gone by and not a word.

Any progress? Four days and not a word from Joomshaper.

Edit: I CAN make this work with a content component which has no difficulty finding the category and rendering a page (which proves this is a Konstra bug), but I lose the main reason for choosing Konstra in the first place, the alternating top-bottom images of the blog layout.

Edit: In the hidden field above, I have changed the default Konstra blog with the error and stack trace to a new url, and deployed a component to temporarily display a working blog.

Hi there,

Thanks for contacting us. Sorry for the inconvenience. Assist me to find out the issue. Where exactly should i go to find out the issue.

500 behavior: caption not found (front end)

500 behavior: framework not found (a back end item)

-Thanks

Thank you for responding. Answer in hidden content area below.

Solved. Please check now. Thanks

Thanks toufiq. Looks good. Did this require new coding from your team or was it some mistake we made here?

Edit: I see an unusual class on the leading item and I needed to add display: flex to it. (screenshot link in hidden area)

Back to normal.

Glad to know that your problem has been solved. Thanks
