Question All posts that have attachments are loaded for a very long time

Does this page work at all?
shepetivka.com.ua/forums/zahalni-temy/84...mista.html?start=120

Here such errors are not from the conflict of css

Does this page work at all?

It's randomly, once yes then no. But when yes, until everything is loaded, it loads more than 10 sek.

Page without attachments

Page with attachments

At that, the load on the server processor does not increase

Have you found the problem? I've tried your posted links 4h ago and now again. The page loads normal for me. Only the Sendpulse plugin loads slightly longer.

The kunena component itself is long generated.

similar issue,
only on pages with attechements,
started after servers IP change that shouldn't have any influence...

solved,
server misconfiguration,
thx

what exactly was fixed?

The issue is only on https://

The solution would really interest me too.
Too bad that a user who has been tried to help, finally not communicated the solution of the community.

Hello.
I have same problem ... forum worked well over a long time, but suddenly it became bad to load threads.
Site server and settings hasn't changed.
Previously, kunena worked perfectly ... now it suddenly gives out a 504 error on topics with a large number of attachments.
PHP 7.1, CMS Joomla 3.9.4, Kunena 5.1.10.1, website address www.akiac.ru/forum.html .
For example, here - www.akiac.ru/forum/school/34-perevod-uchebnogo-goda-v-doo.html
How to solve this problem?

Привет.
Появилась такая же проблема... после долгого использования форума он неожиданно стал плохо грузить темы.
Сайт всё время находится на одном и том же сервере и никаких изменений в настройках не производилось.
Раньше kunena работал отлично... теперь вдруг выдаёт 504 ошибку на темах с большим количеством вложений.
PHP 7.1, CMS Joomla 3.9.4, Kunena 5.1.10.1 , адресс сайта www.akiac.ru/forum.html .
