This applies custom themes in Portal 8 that based on Page Builder theme migrated from Portal 7. User may notice strange behaviour with some of the icons with the Search center. The most obvious one will be a magnifier glass next to searchbox dialog or button even when the search query and returned results are otherwise functional. These weird multiple icons behavior are caused by a missing css class called wpthemeAltText
This specific style/class is not included in Portal 8 by default. So use may have to account for the by including it in their custom css. Here will be a sampel entry
Notes: In portal 8 the applicable style at the location is lotusAltText.
So for example Searchbox.html in <profile root>\installedApps\dev01\PA_Search_Center.ear\searchCenter.war\js\ibm\portal\search\SearchCenter\templates will have following entry in default Portal 8 theme
In Pagebuilder themes from Portal 7 here is the equivalent entry
You therefore basically have to account for it in Portal 8 as described above OR change the line to match what is already in portal 8
