New admin login algorithm

As of version 7.2 of PHP the mcrypt library is moved to the PECL environment.

Its usage is highly discouraged. Now the Sodium extension should be used.

In order to meet the most different server configurations worldwide,

the complete Sphider-plus admin backend and datatabase login scripts were rewritten


New xlsx converter

Now covering also the cell parameters of EXCEL sheets.

As per default the new converter is not activated. It might create too many keywords,

which are not required beside cell content.

In order to activate the converter, rename the default converter


and rename the new one from

.../converter/xlsx_reader_new. php




Updated black IPs list files.

Updated and corrected Italian language file.

Updated IDNA converter required to accept non ASCII URLs.

Replaced deprecated PHP functions (v.7.2+) like 'each()'.


Bug fixed in sub menu 'Settings Backup Management'.

Bug fixed in admin 'Lock out'.

Some HTML improvements. On the way to HTML 5.

Some more small bugs fixed.



Involved folders and files that have been modified / added for this release:
