Hello,
according to Your messages from emails and forum:

1.„Seems that this issue is caused by unclosed HTML tag in one of your
product description. Please check it.”

All HTML tags in product descriptions are closed. Here is table short description, which is not working in hotspot:

<table>
<tbody>
<tr>
<th>Pojemność</th>
<td>2.400 mAh</td>
</tr>
<tr>
<th>Wbudowane złącza</th>
<td>Lightning</td>
</tr>
<tr>
<th>Wbudowane porty</th>
<td>micro USB</td>
</tr>
<tr>
<th>Dodatkowe funkcje</th>
<td>Doskonała ochrona dla iPhone 6s/6</td>
</tr>
<tr>
<th>Certyfikaty</th>
<td>Apple MFi, MIL-STD 810G-516.6, CE, KC, FCC, RoHS</td>
</tr>
</tbody>
</table>

The issue happens only with short description which is table like this, in every product with table description. Products with text description works fine.

2. “Please deactivate all the plugins not related to the theme provide the
site admin access to the private area.”

There are only few plugins not related to the theme like:
– WooCommerce
– Yoast
– Advanced Custom Fields PRO
– All-in-One WP Migration
– Loco Translate
– W3 Total Cache

3. “You have provided one and the same URL twice please check and provide
the product URL and URL with the image hotspot.”
https://nowa.iwalk.pl/portfolio/kolekcja-iwalk-2018/ – all hotspots with text description are working good
https://nowa.iwalk.pl/portfolio/kolekcja-iwalk-2019/ – 3 hotspots with text description and 1 with table description. The page is not working. If You will switch on develop mode in Your browser and switch opacity from 0 to 1 in .vc_row[data-vc-full-width].vc_hidden class, You will see what happens.
https://nowa.iwalk.pl/produkt/obudowa-chameleon-immortal-i6-2400mah-czarny/ – this product is added to hotspot and is not working. We have tried to add different products with short description as a table and every one are not working.
