By the way, I noticed that your website loads very slowly, so you might want to take note of that as well.
There are some online tools that can help you identify the cause of the problem, such as
GTmetrix or
Google PageSpeed Insights.
Usually, that is related to the code and image because sometimes, if the image has a big or medium size, that can make the site load slowly. @OP can start checking his site, all of the pages on his site using the online tools to know what needs to be fixed.
SEMRush is a good online tool to check his website performance and I suggest he use the paid service as the paid service gives everything he needs. Or, if he has a team capable of checking the website performance, he can ask them to check it and fix it.
