I had the white screen after installing the last update, but the helper file you attached in another discussion fixed that. The problem is that now, when I try to save an article, the article is saved but I get a white screen instead of returning to the article. Here is the error that is generated.
Fatal error: Call to undefined function iconv() in /home/xxxxxxx/public_html/administrator/components/com_finder/helpers/indexer/parser/html.php on line 36
Any idea what is going on?
