i am trying to install a new theme in WordPress.I get a message that says "The link you followed has expired. Please try again."No matter what theme I try to install.

i add the following line to the code according to some solution on the internet
but still, I get the same error"The link you followed has expired. Please try again"

```
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

```
