Datalife Engine - Türkçe Destek ( DLE )

MaRZoCHiBugün is right, the theme incompatible is the correct answer. DLE changed the bbcode structure from direct img to css image background on DLE 9.8, so the issue in your case is you are using theme 9.7 or older on DLE 9.8 and newer, this case is always happening so you must upgrade your theme to your recent DLE version

Find:

.editor textarea {
font-family: Verdana;
word-spacing: 0.1em;
letter-spacing: 0;
line-height: 1.5em;
font-size: 11px;
color:#000;
background: #fff url("../images/fields.png") repeat-x;
border: 0 none;
}
.editor input[type="text"] {
padding: 2px;
background: #fff url("../images/fields.png") repeat-x;
border: 1px solid #bcc0c2;
}
.editor_button {
float: left;
cursor: pointer;
padding-left: 0;
padding-right: 0;
}
.editor_buttoncl {
float: left;
cursor: pointer;
padding-left: 1px;
padding-right: 1px;
border-left: 1px solid #bbb;
border-right: 1px solid #bbb;
}
.editbclose {
float: right;
cursor: pointer;
display: none;
}
.editor_button select {
font-size: 11px;
}
.editor_button img {
margin: 0;
padding: 0;
}
.editbclose img {
margin: 0;
padding: 0;
}
.editor_button_brk img {
margin: 0;
padding: 0;
}

You can find the step by step upgrade guide on dleguide.com, if you can't understand and not sure what is your theme version then you can provide a few theme files I can help identify correct theme version so you can upgrade all parts to be fully compatible

engine css dosyasından yapıyormus cok sağolun

tema klasörü dosyaları için de "bbcodes" klasörü eksik.
başka bir temadan alıp o tema dosyası içine atınız.

Sorun tema sürümü ile ilgili fakat sitemizde olan güncellemelerden daha eski sürüm için olabilir. Onun yerine default temadaki engine.css yi deneyin. Eğer sorun çözülürse css lerden bbcode ile ilgili olanları ayıklayıp kendi temanıza ekleyin.
