Translating: I translated and plogger put error message in my page, any help?

Well, my translation is working properly, but in top of my page there is error like this which says that something is wrong.

Notice: Undefined property: gettext_reader::$ORIGINALS in /home/aaapeehe/public_html/toimintojentalo/testi/plog-includes/lib/gettext/gettext.php on line 83
Notice: Undefined property: gettext_reader::$TRANSLATIONS in /home/aaapeehe/public_html/toimintojentalo/testi/plog-includes/lib/gettext/gettext.php on line 94

I don't get what's the problem so can anyone help? There is the code but I just dont get it since I havent touch it at all so the code is original.

81 function load_tables($translations=false) {
82 // if tables are loaded do not load them again
83 if (!is_array($this->ORIGINALS)) {
84 $this->ORIGINALS = array();
85 $this->STREAM->seekto($this->originals);
86 for ($i=0; $i<$this->total; $i++) {
87 $len = $this->readint();
88 $ofs = $this->readint();
89 $this->ORIGINALS[] = array($len,$ofs);
90 }
91 }
92
93 // similar for translations
94 if ($translations and !is_array($this->TRANSLATIONS)) {
95 $this->TRANSLATIONS = array();
96 $this->STREAM->seekto($this->translations);
97 for ($i=0; $i<$this->total; $i++) {
98 $len = $this->readint();
99 $ofs = $this->readint();
100 $this->TRANSLATIONS[] = array($len,$ofs);
