I’ve been installing wordpress on a subdomain of an already existing static website www.example.com for my friend. I have installed it correctly on a subdomain www.sub.example.com, then he asked me to install some custom plugin of his another friends making. I wasn’t able to install it through a panel and when I uploaded it to plugins file through ftp it was not visible in the panel, so I suggested him that there might be something wrong with the plugin.
Today he contacted me and said, that he has called (so he cannot copy paste me the conversation) tech uspport of the website host (godaddy) and suppousedly they told him that wordpress cannot be installed on a subdomain of an already exisiting static website, because there might be some code confilcts. I’m sure I have installed it correctly as I have done it many times before, also on subdomains, but I’m no expert on serwer side issues.
Is this true that I can’t install wordpress on a subdomain, if there is a static website on a main domain? If it’s true, are there any workaround?
