The theme has been installed without any issues. The plugins have also been installed.
But there has been a blink in between this. When I load the website, it returns and error 500.
Again, when importing demo data, the hosting must be connected with our server throughout the whole time.
Please contact hosting support, if you have bought it from someone.
Inform them – “The site gives error 500 every now and then, when browsing”
If you have a self hosted website, please contact the support engineer for keeping the hosting alive.
There might be issues regarding the writing permissions on your hosting.
