Hi,

Today, when trying to generate manual backups, I am having a problem I have never
had before.

I get the following error message:


There was an error retrieving the JSON data from the server, try again or
contact the developers!

Details: error — undefined

JSON url:
index2.php?task=recurse_database&nohtml=1&dbbackup_comp=&dbbackup_drop=&startAtLine=19&startAtRecord=0&dumpfile=/home/xxxxx/public_html/yyyyy/administrator/backups/database-sql.sql

If I click “Retry” immediately, nothing happens but if I wait about 5 seconds,
the backup progresses for a while before being stopped again:


There was an error retrieving the JSON data from the server, try again
or contact the developers!

Details: error — undefined

JSON url: index2.php?task=recurse_files&mode=&nohtml=1

And then:


There was an error retrieving the JSON data from the server, try again or
contact the developers!

Details: error — undefined

JSON url: index2.php?option=com_cloner&task=refresh&json=1&startf=100&lines=3603&backup=backup_2013-06-01_16-36_example.com-sql-nodrop.tar&excl_manual=

And then many other error messages.

So, I have to click about 30 times for the backup to complete.

As mentioned above, I have never had this problem before.

I have other blogs on the same hosting but on a second account and on another
server. There are no problems for those blogs.

I tried and reduce the “Files to process per request:” to 10 but unsuccessfully.

Finally, after switching the “Backup Refresh Mode” from AJAX to Normal I could
generate several backups without any error message.

So, what’s going on?

Like for the timestamp change I mentioned in another post, I notice that this
problem occurs after the latest update.

That error usually indicates a timeout on script execution, i would advise to check with your hosting support. XCloner has the option to decrease the backup load by processing less items, so check the XCloner Config->System tab, you will be able to decrease the files to process per session as well as the mysql table data.

Hi,

I have already tried all that unsuccessfully.

The only thing that works is using “Normal” instead of “AJAX” for “Backup Refresh
Mode”.

I’ll check with my hosting anyway but I don’t understand why other blogs on the
same hosting don’t encounter such problems.
