Try to install the theme via FTP: https://forum.tagdiv.com/install-via-ftp/
Provide a link to your website.
Try to activate the Theme manually:

By default, once you have installed it, the tagDiv AMP plugin becomes active on posts. For pages, you have to activate it by switching ON the option.

.td-icon-views {
display: none;
}

Try to clear your cache or browser cache.
Just press save button:

Try this:
.td-scroll-up {
background-color: yellow!important;
}
A waste of time.
No plugin will prevent you from viewing the source code of page in the browser.
For example:
Google Chrome: Ctrl + Shift + I
FireFox: Ctrl + U
After disable all untested plugins clear modifications of core files or install the Theme again.
Try to activate the Theme manually:

My web pages show the date in the publications, except for one.
You’re wrong. You have a lot of pages where there is no date. For example:
https://soyunperro.com/signos-miedo-perros/
https://soyunperro.com/perros-predecir-muerte/
https://soyunperro.com/perro-molesta-sople/
and so on.
If you are using some untested plugins, try to disable all of them and leave just to active only the plugins that come bundled with the theme core files and check the results.
