The first thing I would do is to open the JavaScript console and, possibly the Network tab, in the Developer tools. Check for any error conditions.

Again - you posted a file that looks like real data so I have delete it.

However, all lines had both a trailing comma and quotes around the whole line. It also had spaces in "first name" and "last name" (check the docs for the csv format). Won't work. E.g. the header looked like this...

"username,first name,last name,email,password,"

It should look like...

username,firstname,lastname,email,password

The most reliable way I have found to create CSVs is to use LibreOffice (https://www.libreoffice.org/). Use the spreadsheet program and "save as" CSV.

Have a look at the file in a text editor and make sure the formatting is really correct - no weird characters, trailing commas and so on.

But, as Mary says, give us a minimum *anonymous* file that exhibits the problem and we'll check it out.

Again - the simplest "do something" solution is probably to switch to Redis.

Also to note 'memcache' and 'memcached' are different things (with insane naming)
